Kaplan has been in the test prep business for over 80 years. It was, by its own account, the company that invented SAT prep, and its brand recognition remains among the strongest in the industry. When families start researching SAT or ACT courses, Kaplan is almost always on the list.
The question worth asking carefully is not whether Kaplan is a known brand. It clearly is. The question is whether the format it primarily delivers — group classes of 15 to 20 students, rotating instructors, and self-paced on-demand content — is the right fit for your teen's specific score goal, learning style, and the six subjects they may need to cover across high school.
Catalyst Test Prep takes a fundamentally different approach: live 1:1 sessions with a single dedicated tutor for every session, a personalised study plan built from a diagnostic at enrolment, monthly progress reports for parents, and a score improvement guarantee across all six of its programmes. The comparison below covers every subject, the structural differences that determine outcomes, and how to decide which programme fits your teen's situation.
Before going subject by subject, this distinction is worth addressing directly because it shapes every other comparison on this page.
Kaplan's Live Online classes are group sessions. Instructors — often multiple per class — teach content to a room of students, answer questions from the group, and move through a shared curriculum at a pace designed for the average student in that session. Kaplan explicitly markets "multiple teachers per class" as a selling point. For many students, a well-run group class is a perfectly effective way to learn.
But group instruction has a structural ceiling. The instructor cannot observe your teen's specific reasoning process across every question. They cannot build up a session-by-session picture of which error patterns keep recurring and why. They cannot slow down on the exact sub-type of question your teen keeps missing while accelerating through material they already understand. The lesson moves at the class's pace, not your teen's.
Catalyst's sessions are 1:1 from start to finish. The same tutor works with the same student for every session, builds a detailed understanding of their specific gaps and patterns over time, and adjusts the plan based on how the student is actually progressing — not how a hypothetical average student at that level would be expected to progress. For a deeper look at why this distinction matters for outcomes, see our guide to 1:1 SAT tutoring vs. group classes.
Kaplan's SAT offering is one of the most comprehensive in the industry at its price point. The On Demand course starts at around $200 and includes approximately 50 video lessons, 500-plus practice questions, and 4 full-length Digital SAT practice tests. The Live Online course adds 18 hours of group instruction from 99th-percentile-scored instructors and is priced at around $700 to $800. A Bootcamp option exists for students with two to three weeks before test day, at around $800.
Kaplan's video production quality is consistently rated among the best in the industry — short, focused, and well-structured. The "Learn It, Drill It, Prove It" system used across its curriculum is well-designed for students who benefit from a clear step-by-step progression.
The score guarantee applies across most Kaplan SAT courses: higher score or full refund, subject to completing specific course milestones including a minimum number of practice questions and full-length tests.
Where group Live Online reaches its limit is the same place all group instruction does: it cannot catch why a specific student keeps losing points on, say, "words in context" questions or multi-step algebra problems involving functions. It can teach the strategy for those question types — and Kaplan does that well — but it cannot observe the individual student applying that strategy and identify exactly where the execution goes wrong. That gap is where 1:1 instruction changes outcomes.
Catalyst's SAT programme is built around a diagnostic that maps the student's exact starting point, a personalised plan targeting their highest-priority gaps, and live sessions where the tutor watches and corrects the student's thinking in real time. See our SAT online classes page for full programme details.
This is where Kaplan has a genuine competitive advantage. Kaplan is the official partner for live online ACT prep, which means it has access to real ACT practice questions that are exclusive to Kaplan's platform — content that no other prep company can offer. For students who want to practise on authentic ACT material, that partnership is meaningful.
Kaplan's Live Online ACT students who complete the full programme — defined as at least 1,200 practice questions and 3 full-length timed exams — improve by an average of 4 points. That is a documented outcome from a programme with official content, and it is competitive with most alternatives at the group class price point.
The structural limitation remains the same: group instruction. The ACT Science section in particular is one where individual coaching tends to make a significant difference. Students approach ACT Science with different underlying confusions — some are misreading the passage structure, some are allocating time poorly across passages, some are missing the experimental reasoning logic. A group class teaches a shared strategy. A 1:1 tutor identifies which specific confusion is costing your student points and addresses that directly.
Catalyst's ACT programme covers all four sections with live 1:1 instruction, a personalised study plan, and a score improvement guarantee. Details on Catalyst's ACT online classes are available on the course page.
Kaplan does not offer a standalone PSAT course. PSAT preparation is included as part of the Unlimited Prep and College Advantage bundle packages, which combine SAT, ACT, PSAT, and AP content into a single extended-access product. Students who want only PSAT prep from Kaplan have to purchase the full bundle to access it.
Within the bundle, PSAT content is delivered in an On Demand format — self-paced video and practice, not live instruction. For students whose PSAT goal is a general score improvement, that may be sufficient. For students targeting National Merit Scholarship Programme eligibility — where the qualifying threshold is state-specific and sitting in the top 1 percent of scorers requires deliberate strategic preparation — a bundled on-demand module is unlikely to provide what a structured, targeted plan actually requires.
Catalyst's PSAT preparation is a dedicated programme built around the current Digital PSAT format, the student's individual target score, and the specific Selection Index thresholds relevant to their state. See our PSAT online classes for full details.
Kaplan offers a live AP Calculus AB and BC review course that covers both exams in a single programme. The course includes 8 live instructor-led group sessions, self-paced modules, digital flashcards, quizzes, and full-length practice exams. Recorded sessions are available for students who miss a live session or want to review material later.
This is a more substantial AP offering than most competitors at a comparable price point, and for students who engage consistently with the live sessions and self-paced materials, it covers the conceptual content of both exams reasonably well.
Two limitations are worth noting. First, reviewers consistently observe that Kaplan's AP Calculus coverage may not go deep enough on the most advanced BC topics — particularly series convergence, parametric equations, and polar functions — which carry significant exam weight. Second, and more structurally significant: the group format means FRQ preparation is not personalised to each student's written work.
As with all AP exams, free-response questions account for approximately 50% of the AP Calculus AB and BC score. FRQ performance depends not just on conceptual understanding but on written mathematical communication: correct notation, step-by-step justification, and clear logical structure scored against explicit College Board rubrics. In a group class, the instructor can demonstrate how FRQs should be approached and show model answers. What they cannot do is review each student's individual written responses, identify where that specific student's notation or justification is costing points, and correct it before the next session. That is what 1:1 instruction provides.
Catalyst's AP Calculus AB and BC programmes are built around live sessions that include dedicated FRQ coaching — working through the student's own written responses against College Board rubrics and correcting the specific errors that appear in their work. Full programme information is on the AP Calculus AB and AP Calculus BC course pages.
Kaplan's AP Physics presence consists of free study resources and blog articles on its website. There is no dedicated live AP Physics course available for public enrolment through Kaplan's standard course catalogue.
For students in AP Physics 1, AP Physics 2, or AP Physics C, this means Kaplan cannot serve as a preparation programme for that subject. The free articles cover individual concepts and are useful for quick reference, but they do not constitute a structured preparation plan with live instruction, timed exam practice, or FRQ coaching.
AP Physics 1 consistently records one of the lowest pass rates of any AP exam — typically around 42 to 48 percent scoring a 3 or above — reflecting the difficulty of the subject and the inadequacy of light-touch prep for a course that integrates conceptual reasoning, mathematical problem-solving, and experimental analysis in the same questions. The FRQ section of AP Physics exams includes experimental design and scientific argumentation tasks that require specific written skills beyond content knowledge alone.
Catalyst covers AP Physics through live 1:1 instruction that goes beyond concept review: multi-step problem practice, experimental design coaching, and FRQ preparation from a tutor who knows exactly where each student is struggling.

Kaplan's pricing structure is tiered and relatively transparent. The On Demand self-paced SAT course starts at around $200. The Live Online group course runs from approximately $700 to $800. A Bootcamp for last-minute preparation is around $800. The Unlimited Prep bundle — which includes SAT, ACT, PSAT, and AP content, 5 hours of 1:1 tutoring, and college advising — is Kaplan's most comprehensive package and represents a significant investment, though pricing varies and the company runs regular discounts.
Additional 1:1 tutoring beyond what is included in a bundle can be added at around $300 for 3 hours — which works out to $100 per hour. That rate is positioned as affordable relative to the broader tutoring market, but it also makes clear that 1:1 instruction is a premium add-on within the Kaplan model, not the core of the product.
Catalyst is a paid 1:1 live programme with pricing based on the student's subject, target score or grade, starting baseline, and timeline to test or exam day. Every session is live and 1:1 from the first one. There is no self-paced base product with tutoring bolted on top.

Not as a standalone programme. Kaplan's core formats are self-paced On Demand and group Live Online classes with 15 to 20 students per session. A small amount of 1:1 tutoring — 5 hours — is included in the top-tier Unlimited Prep bundle, or available as a $300 add-on (3 hours) on other plans. Catalyst Test Prep provides dedicated 1:1 live instruction for every session across all six of its programmes, with the same tutor throughout.
Kaplan offers free AP Physics study resources and blog articles but does not have a dedicated live AP Physics prep course available for direct enrolment. Students needing structured AP Physics preparation — including FRQ coaching, timed exam practice, and multi-step problem strategies — will need to look beyond Kaplan's publicly available course catalogue. Catalyst covers AP Physics through live 1:1 instruction with a dedicated tutor.
Kaplan offers a higher score guarantee on most of its courses: if your score does not improve after completing the programme, you can receive a full refund or free course extension. The guarantee requires completing specific course milestones, including a minimum number of practice questions and full-length tests. Catalyst offers a score improvement guarantee across its 1:1 live programmes, backed by a dedicated tutor who is actively managing the student's progress throughout — not a refund condition attached to a self-paced product.
Kaplan's Live Online classes are group sessions with 15 to 20 students, led by instructors who may rotate across sessions. Kaplan markets "multiple teachers per class" as a feature. Catalyst's sessions are 1:1 with the same dedicated tutor for every session. In a live group class, instruction is designed for the average student in the room. In a 1:1 session, every minute is spent on that specific student's gaps, errors, and score goal.
No standalone PSAT course. Kaplan includes PSAT prep as part of its Unlimited Prep and College Advantage bundle packages, delivered in On Demand format. For students targeting National Merit Scholarship eligibility — where state-specific Selection Index thresholds require strategic preparation — a bundled on-demand module is unlikely to provide the targeted planning that dedicated 1:1 PSAT instruction offers.
Kaplan is one of the most established SAT prep providers available, with 80-plus years in the industry and video lessons rated among the best-produced in the space. Its On Demand course starts at around $200, and Live Online group classes offer structured instruction at a fraction of 1:1 tutoring costs. For students who learn well in group settings and want a structured curriculum, Kaplan is a credible option. Its main limitations are the group format and the limited availability of dedicated 1:1 instruction within standard plans.
Yes. Kaplan offers a live AP Calculus AB and BC review course with 8 instructor-led group sessions, self-paced modules, and full-length practice exams. Recorded sessions are available for review. However, reviewers note that advanced BC topics may not receive sufficient depth, and the group format means FRQ feedback is not personalised to each student's individual written work. Free-response questions account for roughly 50% of AP Calculus exam scores.
Kaplan is the official partner for live online ACT prep, giving it exclusive access to real ACT practice questions. Live Online ACT students who complete the full programme improve by an average of 4 points. Catalyst provides live 1:1 ACT instruction with a dedicated tutor covering all four ACT sections, including Science, with a personalised study plan and score improvement guarantee. The key difference is group instruction with official content versus dedicated 1:1 instruction personalised to the student's specific patterns.
Kaplan's Unlimited Prep package includes SAT, ACT, and PSAT On Demand courses, live SAT and ACT class access, AP prep materials, 5 hours of 1:1 tutoring (for SAT, ACT, or AP only), 6 hours of college advising, and access until June of the student's senior year. It is Kaplan's most comprehensive package and bundles several products together, though it represents a significant cost compared to standalone course options.
Catalyst provides live 1:1 instruction with the same dedicated tutor throughout the programme, a personalised study plan built from a diagnostic, monthly parent progress reports, and a score improvement guarantee. Kaplan's core offering is group classes and self-paced content, with 1:1 tutoring limited to a small add-on. For students who have plateaued on group-format prep, are targeting competitive scores, or need preparation for AP Physics where Kaplan has no live course, 1:1 instruction tailored to the individual student produces more reliable improvement.
Kaplan's 80-year track record is real, and its product quality reflects it. Strong video lessons, official ACT content, a clear curriculum structure, and a score guarantee make it a legitimate choice — particularly for students who learn effectively in group settings and are primarily preparing for SAT or ACT.
But Kaplan's core model is built around groups. The 1:1 tutoring that produces the most reliable improvement in individual students exists at the margin of Kaplan's offering — a few hours tucked into a bundle, or a $300 add-on. For students who need more than a well-run group class, that structure has a ceiling.
Catalyst's entire programme is built around what Kaplan offers as an add-on: a dedicated tutor, working 1:1 with the same student for every session, accountable for that student's progress, and available across all six subjects your teen may need — including AP Physics, where Kaplan has no live course to offer at all.
If your teen is ready to move beyond group content and into instruction that adapts to them specifically, a free consultation is the right starting point.
Live 1:1 instruction across SAT, ACT, PSAT, AP Calculus AB, AP Calculus BC, and AP Physics — all with a dedicated tutor and a score improvement guarantee. Book a free consultation to see exactly where your teen stands and what a personalised plan looks like.
