Mometrix MCAT Prep Book 2026-2027 (MCAT Secrets Study Guide) Review

Mometrix MCAT Secrets costs $51.99 as an ebook or $56.99 in print, which makes it the cheapest complete MCAT book we track by a wide margin. It is worth buying as a strategy supplement and as a cheap source of 3 full-length practice tests. It is not worth buying as the book that teaches you the MCAT.

Most reviews of this guide stop at "cheap and thin", which is true and not very useful. The questions that decide whether this is a good $52 are which of the two formats to buy, what the money-back guarantee actually covers, and whether Mometrix's own store sells you the current edition at the best price. The answers are not the ones the marketing implies. Everything below was read on Mometrix's own pages on 14 September 2026.

Mometrix MCAT Secrets Overview

Mometrix is a general test-prep publisher. It sells single-volume Secrets guides for hundreds of exams, from nursing boards to civil service tests, and the MCAT guide follows the same house format: a strategy section, a condensed review of each tested area, practice questions with worked explanations, and links out to short instructional videos.

That format is the product's whole character. This is not a seven-book subject review that walks you through biochemistry from the beginning. It is one volume that tells you what the exam asks for, shows you how the question types work, and gives you material to practise on. Read it that way and it does its job. Read it as a replacement for a content set and you will be underprepared.

The current release is the 9th edition, published on 8 November 2025 and branded "MCAT Prep Book 2026-2027". Here is what the price includes:

• A single-volume guide covering all four MCAT sections
• 3 full-length practice tests, all 3 in an online interactive format, with 1 of them also printed in the book for offline work
• Answer explanations written out in full for the practice questions
• Step-by-step video tutorials on Mometrix Academy, reached through codes printed next to the relevant concepts
• A test-taking strategy section built around what Mometrix calls the 5 Secret Keys
• Two bonus reports, one on study skills and one on overcoming test anxiety

And what it does not include:

• Any question bank you can filter by topic or difficulty
• Any AAMC material, which is the only practice that tracks your real score
• Any scheduled instruction, tutoring or coaching
• Colour printing, so diagrams arrive in black and white
• Any published access period for the online component

Mometrix MCAT Prep Book Review For 2026

One volume against the most content-heavy exam in admissions

The MCAT tests biology, biochemistry, general chemistry, organic chemistry, physics, psychology and sociology, plus a reasoning section with no content at all. Competing sets cover that with seven to ten books. Mometrix covers it with one.

The compression is handled honestly. Mometrix does not pretend the guide is exhaustive: the section outlines on its own page are lists of topic headings, and the text is written to remind and to frame rather than to teach from zero. If you took these courses recently and need a map of what the AAMC expects, that is a real service and it is faster to get through than 3,000 pages.

If a subject is genuinely new to you, this book will not fix it. Organic chemistry and physics in particular need worked depth that a shared volume cannot give, and the black and white diagrams hurt most exactly there. Plan to pair it with a full set from our MCAT prep books roundup, or with the free equation sheets and content checklist in Blueprint's free library, which cost nothing and overlap usefully with what Mometrix compresses.

The 3 full-length tests are the part that punches above the price. Three tests for $56.99 works out to about $19 a test, and all 3 run in an online interactive format that scores them for you. They are not AAMC exams and they will not predict your score, so treat them as timing and stamina practice and budget separately for official material from AAMC's practice tests.

The guarantee is the selling point, and the format you pick decides what it is worth

Every roundup that mentions Mometrix, including our own until today, cites the 1-year money-back guarantee as the thing no other MCAT book publisher offers. The sales page states it plainly: risk-free, 1 year, 100 percent money back, returnable at any time for any reason up to one year after the purchase date, no hassle and no questions asked.

The store's own refund policy is narrower, and it is the page that governs your order. It returns physical products up to one year after purchase, and digital products within seven days of purchase.

The ebook is a digital product. So the cheaper option, the one a budget-driven buyer reaches for first, carries a refund window 358 days shorter than the one being advertised, for a $5 saving.

Neither figure is hidden and neither is dishonest on its own. They simply sit on two different pages, and the page that makes the promise is not the page that sets the terms.

The sales page is describing an MCAT that no longer exists

One thing to know before you trust the guide's framing. The sales page tells readers that an MCAT score "can be broken down into individual subtest scores on the Verbal Reasoning, Physical Sciences, Writing Sample, and Biological Sciences sections". Those are not the sections of the current exam. Mometrix's own store listing for the same book, linked in the summary table above, names the four sections correctly: Biological and Biochemical Foundations of Living Systems, Chemical and Physical Foundations of Biological Systems, Psychological, Social, and Biological Foundations of Behavior, and Critical Analysis and Reasoning Skills. The sales page carries a "last updated" stamp of 7 August 2026.

This does not mean the book is out of date. The store listing, the section outlines and the edition date all point at current material, and the two pages are maintained by different parts of the business. It does tell you what kind of publisher you are buying from: one that runs a template across hundreds of exams, where the marketing copy is not audited as closely as the product. That is worth knowing when you are weighing the guide's claims about itself, and it is a fair reason to trust the book for strategy and to verify content against a primary source.

Pricing

Mometrix sells direct and lists both formats of the current edition at a sale price against an $88.99 regular price.

The same 9th edition guide in both columns. The $5 price gap is the only difference students notice, and the refund window is the difference that matters.

Two things in that table are worth acting on. The first is that the used-and-older trick fails here: Mometrix's store search still lists the 7th edition printed book at $64.99, which is $7.99 more than the current 9th edition, and the 7th edition ebook at $59.99 against the current $51.99. If you search the store and sort by nothing in particular, it is easy to land on an older, dearer listing. Buy from the edition marked 2026-2027.

The second is that the flashcards and the boxed study cards are separate purchases at $53.99 and $88.99. Buying the guide plus the boxed cards costs more than a mainstream seven-book set, which is not a trade we would make. If flashcards are what you are short of, the free and paid decks in our MCAT flashcards roundup are better value.

At $56.99 for the print edition you are paying roughly $19 per full-length test and getting the guide itself for nothing, which is the fairest way to read this price.

Who Mometrix MCAT Secrets Is Best For

• Students on a hard budget who need something structured and cannot spend $200 on a box set
• Recent science graduates who want a map of what the AAMC tests rather than instruction from the beginning
• Second-resource buyers who already own a content set and want cheap full-lengths and a strategy section
• Students who want a safety net, as long as they buy the printed book and keep the one-year return
• Anyone testing the water before committing to a full MCAT study schedule and the spending that comes with it

When You Might Look Elsewhere

• If this is your only resource and you are starting from scratch, the Kaplan 7-book set teaches the content properly and flags what the AAMC tests most
• If you need practice volume rather than reading, the Examkrackers Complete Study Package carries far more online exams than any single guide can
• If retention is the problem, the UWorld books are built around integrated illustrations and include two books on CARS alone
• If your budget is actually zero, start with our free MCAT resources rather than spending $52 on a supplement
• If you want to know how we weigh price against evidence, our review methodology explains what we count and what we ignore

Final Verdict

Mometrix MCAT Secrets does one thing well and says it does more. The one thing is giving a budget-constrained student a structured strategy guide and 3 full-length tests for the price of a textbook chapter, and at about $19 a test that is honest value. The overstatement is in the framing: a single volume against the MCAT's content load is a supplement, and the sales page around it is template marketing that has not been read closely in years.

The evidence base is also thinner than the star ratings suggest. There is very little discussion of this guide among actual MCAT students, which is not an accusation, but it does mean you are buying on the publisher's word rather than on peer experience.

If you are still deciding what your whole prep should cost, the comparison in our MCAT prep books roundup sets this guide against the full sets, and the MCAT hub covers scoring, timing and everything else about the exam.

Mometrix MCAT Prep Book FAQs

How much does the Mometrix MCAT prep book cost?

$51.99 for instant ebook access or $56.99 for the printed book, both sold direct by Mometrix against an $88.99 regular price, as of 14 September 2026. There is no cheaper tier and no subscription. Note that Mometrix still sells older editions of the same guide at higher prices, so check that the listing you are buying is the 2026-2027 9th edition.

Is the Mometrix MCAT guide enough on its own?

No. It is a single volume covering an exam that competing publishers cover in seven to ten books, and it is written to remind and to frame rather than to teach a subject from scratch. Use it for test-taking strategy, for a map of what is tested, and for the 3 full-length practice tests. Pair it with a full content set and with official AAMC practice material.

Does the Mometrix money-back guarantee cover the ebook?

Not for a year. Mometrix advertises a 1-year, no-questions-asked money-back guarantee on the product page, but its store refund policy returns physical products up to one year after purchase and digital products within seven days. The ebook is a digital product, so it carries the seven-day window. If the guarantee matters to you, buy the printed book.

How many practice tests come with the Mometrix MCAT book?

Three full-length practice tests. All 3 are available in an online interactive format that scores you and shows what you got wrong, and 1 of the 3 is also printed inside the guide for offline work. They are written by Mometrix, not by the AAMC, so use them for pacing and stamina and rely on official exams for score prediction.

Should I buy the ebook or the printed Mometrix MCAT book?

The printed book, unless you need the content in the next few hours. The $5 saving on the ebook costs you the difference between a seven-day and a one-year return window, and the printed copy typically ships within one business day. The content is identical in both formats, and both include the same 3 online practice tests and the same video tutorial links.
