MCAT CARS course
Two answers sound right. Only one survives the passage.
Red Pen Prep trains the one move that decides CARS questions: finding the sentence that settles it. You answer, you prove it with a sentence from the passage, then the correction shows its work, down to the trap that made the wrong answer look right.

Answer. Prove it. Then the red pen.
Most CARS explanations tell you the answer. This one makes you find the sentence first, then shows you whether you were right to trust it.

Original passages in the real format, timed or untimed, on your phone or a computer.

Prove it
Before any explanation, you tap the sentence that makes your answer right.

See the red pen
The sentence that decides it, why the right answer holds, why each other choice fails.

Catch your traps
Every miss is filed under the trap that caught you, so you see which ones keep winning.

The passage decides. Not a rule of thumb.
You won't hear "extreme words are always wrong" from us. Sometimes the passage supports "always." What decides a CARS question is a sentence, so that's what you learn to find.
When you miss, the course names the trap that made the wrong answer look right, and two transfer problems check later whether it still catches you.
The trap names are our teaching tool, not an official AAMC list. Use the AAMC's official practice material too: it comes from the people who write the exam.
Passage 001 · Paragraph 3
P3Such choices do not make evidence irrelevant. Examination can distinguish original pigment from later material, and letters can indicate why a change was made. These findings constrain responsible decisions. A curator cannot reasonably call an alteration original merely because the altered image is attractive.
Three of the 21 traps
- One rule wins
- One principle the author accepts is applied while the others the author requires are dropped.
- Dictionary meaning
- A word is read in its usual sense instead of the sense the passage gives it.
- Detail for the whole
- A point from one paragraph is offered as the main idea of the passage.

Questions
What do I get when I buy today?
Forty-one original CARS passages. Thirty-two are for practice: you work them one at a time and see the full correction after each question. The other nine make up one timed section in the real format: 9 passages, 53 questions, 90 minutes. Around the passages you get the prove-it step, a review of your misses sorted by trap, and your progress by skill.
Can I try it before I buy?
Yes, and you should. Passage 001 is free, with its six questions, the prove-it step and the full correction, plus two new problems that check the same reasoning. The Trap Scan is free too: 20 two-choice traps in about 5 minutes, and at the end you see the traps that catch you.
Is this official AAMC material?
No. These are original practice passages, not official AAMC material, and the trap names are our teaching tool, not an official AAMC list. Use the official AAMC practice material too; it comes from the people who write the exam.
When do the updates come, and do they cost extra?
They're included at no extra cost. The next update adds a second timed section; later updates take the course to 100 passages with 3 timed sections. Each one goes live once every passage in it has passed our checks, and we don't promise dates. Your license key opens each update as soon as it's live.
Does it work on my phone?
Yes. It runs in your browser, on a phone or a computer, with nothing to install. After you pay, your license key arrives in your receipt email; open the course, enter the key, and your passages open. The key works on up to 3 devices or browsers at a time. Your progress is saved in the browser you work in and doesn't follow you from one device to another.
How does the founder price work?
It's the same course with the same updates, applied at checkout when you use the button on this page. After the founder date, the price is $99. Either way it's one payment, not a subscription.
Who makes the videos?
We do. The questions, passages and corrections are written and checked by us; the voice in our videos is AI-generated, and we say so on every post.
What if it isn't for me?
Write to our support address within 14 days of your purchase, from the email you bought with, and you get a full refund. You don't need to give a reason.
Can you guarantee my score?
No. Nobody can honestly promise you a CARS score, and we won't. The timed section is practice under test conditions, not a score prediction, and the difficulty of our passages hasn't been measured against real exam results. What the course does is make your reasoning visible: which sentence decides each question, which traps catch you, and whether a similar problem still catches you 48 hours later.
