Is AAMC Official MCAT^® Prep Worth Buying?

Every product is online-only and comes with 365 days of access from the day you buy it, according to the AAMC Store's product comparison. The two free full-lengths are listed first for reference.

Two notes on the table. The bundle's own store listing shows $336.15 against a regular price of $405.00, while the comparison table lists $336.70, so expect to pay about $336 either way. And the bundle's 2,876 figure counts unique questions. The products' individual counts add up to 2,955, so 79 questions appear in more than one product.

If your year runs out before test day, you can extend a product instead of buying it again. For a practice exam, a 3-month extension costs $17.50 and a 6-month extension costs $22.75. You have to buy the extension while the product is active or within 60 days after it expires.

Third-party companies write good questions, but they can't copy two things the AAMC has.

• The real scale: The comparison page says the practice exams are the only products with scaled scores and percentile ranks. The other products give you confidence levels instead.
• The real question style: The AAMC's free resources page says Practice Exam 1 uses previously administered MCAT^® questions and has the "same look, feel, functionality, scaled score and percentile rank as an actual exam."

That's why a 505 on an AAMC practice exam means more than a 505 from a prep company. Third-party tests build their own scales from their own students, so their scores don't convert to the AAMC's.

The explanations differ by product. The practice exams, Section Bank Vol. 2 and the CARS Question Bank explain all four answer choices. The other products explain only the correct answer, which matters if you learn the most from figuring out why a wrong answer tempted you.

Here's what 100 questions cost in each product, which shows that the cheapest products per question aren't always the most useful.

The full-lengths cost the most per question, and they're still the best buy, because no other product gives you a score on the real scale. The Independent Question Bank is the cheapest by far, but it has no passages, so it drills facts rather than passage reading.

Work down this list and stop when you run out of time or money.

1. Practice Exams 2 to 6 ($175 for all five): Five 230-question full-lengths, each with a scaled score and a percentile. Together with the free Practice Exam 1 and the Sample Test, they give you seven AAMC full-lengths in all.
2. Section Bank, Vols. 1 and 2 ($90 for both): Each volume has 300 questions, 100 from each science section, according to the AAMC's product overview. That's 600 science questions in AAMC style, sorted by section, which makes them good for drilling a weak section between full-lengths.
3. CARS Question Bank ($70): 575 passage-based questions, of which 166 are new and 409 come from earlier AAMC products. If you already worked through older CARS practice, a large share will look familiar. If you didn't, it's the biggest source of official CARS practice, and the CARS plateau guide explains how to use it without wearing passages out.
4. Biology, Chemistry and Physics Question Packs ($60 for all four): 120 questions each, with explanations for the correct answer only. Buy the packs for the sections where you're weakest.
5. Independent Question Bank ($10): 150 questions, 25 each in biochemistry, biology, chemistry, physics, psychology and sociology. It's cheap, and good for a quick check of facts, but it won't train passage reading.

If your budget only covers one thing, make it the practice exams. Questions without a score can find your weak topics, but only a scored full-length can tell you whether you're ready to test.

The bundle includes all 13 paid products for about $336, which saves you $68 to $69 against the $405 you'd pay buying them one at a time. That's a discount of about 17 percent ($405 minus $336.15 is $68.85, and $68.85 divided by $405 is 17 percent).

The useful comparison is with what you'd buy anyway. Practice Exams 2 to 6, both Section Banks and the CARS Question Bank add up to $335 ($175 plus $90 plus $70). The bundle costs $1 to $2 more than those three items alone and adds the four question packs and the Independent Question Bank, which would cost $70 on their own.

• Buy the bundle if you plan to use the Section Banks and the CARS Question Bank on top of the full-lengths.
• Buy separately if you only want the practice exams, or the practice exams plus one Section Bank. That's $175 or $220, well under the bundle price.

Decide before you buy anything, because the comparison page says that "if you purchase individual products, you cannot upgrade to a bundle later." Time the purchase too. The 365-day clock starts at checkout, so buying a year and a half before test day means paying for an extension later.

Before you spend money, use what the AAMC gives away. Practice Exam 1 and the Unscored Sample Test are free full-lengths, and the free practice test guide explains where they fit in your schedule. The free Content Outline Course now includes 120 practice questions from the retired Official Guide to the MCAT Exam, which Tutorium reports is no longer sold, so you don't need to hunt down a used copy of the book. The AAMC also links its Khan Academy MCAT^® collection, with 1,100 videos and 3,000 review questions.

Check the AAMC Fee Assistance Program before you pay for anything. Recipients can get the Online-Only Bundle for free, but it's an elected benefit, so you have to choose it before the products appear in your Official Prep Hub, as International Medical Aid's MCAT cost guide notes. The same award cuts MCAT^® registration from $355 to $145. The fee assistance guide covers who qualifies and the timing.

The products only pay off if you review them. Plan to spend at least as long reviewing each full-length as you spent taking it, and log every miss by its cause with the full-length review method.

Spread the full-lengths out. Saving all five paid exams for the last two weeks leaves no time to fix what they show you. The MCAT study schedule guide shows where each full-length and question bank fits week by week.

• How much does all of AAMC Official Prep cost? $405 bought separately, or about $336 as the Online-Only Bundle.
• What's the best first purchase? Practice Exams 2 to 6, at $35 each, because they're the only paid tests scored on the real scale.
• Is the Official Guide still sold? No. The AAMC retired it and moved 120 of its questions into the free Content Outline Course.
• How long does access last? 365 days from purchase, with 3- and 6-month extensions available.
• Can I upgrade to the bundle later? No. Individual purchases can't be converted into a bundle.
• Is any of it free? Practice Exam 1 and the Unscored Sample Test, plus the bundle for Fee Assistance Program recipients who elect it.

After each AAMC practice exam, look up what your total and section scores mean in the PurpleCAT MCAT score guide.
