Study Once, Win Twice
The best way to study for your GPA is the same skill that later wins the LSAT. Learn it once.
I’ve told you to protect The Number and pick a major you can win in. I haven’t told you the part that produces the grades: how to study. That’s this chapter, and it comes with a gift. The most effective way to learn for college exams is, underneath, the same approach that later beats the LSAT. So you don’t have to build two skills. You build one, and it pays twice, in your GPA now and your score later.
The way you were taught to study barely works
The misconception that costs more hours than any other is that studying means rereading your notes and highlighting the textbook. It feels productive. You spend three hours, your pages turn yellow, and you feel like you learned. You mostly didn’t.
Rereading and highlighting train recognition, not recall. The material looks familiar when you see it again, so your brain says “I know this.” Then the exam asks you to produce it from a blank page and you can’t. Recognition is cheap and useless under pressure. Producing the answer is the whole game, on a final and on the LSAT both. The students pulling A’s with fewer hours aren’t smarter. They quit doing the thing that feels like studying and started doing the thing that works.
The three moves that build grades
Three evidence-backed moves, and notice as we go that each one is also exactly how you’ll later prep for the test.
Test yourself instead of rereading (active recall). Close the book and try to produce the answer, the definition, the steps, the argument, from memory. Flashcards you quiz yourself on, practice problems with the solutions covered, explaining a concept out loud to an empty room. It’s harder than rereading, and the difficulty is the point. Retrieving a fact strengthens it, recognizing it doesn’t. The LSAT is pure production, calling the answer before you peek at the choices. So every hour of recall you practice in college is also a rep for the test.
Space it out (don’t cram). The same total hours spread across a week beat one panicked night, because each time you let yourself half-forget and then retrieve, the memory sets harder. Cramming gets you through Friday’s exam and is gone by Monday. Spaced practice builds knowledge that stays, which matters in a major where junior-year courses build on sophomore-year ones. It’s also exactly how LSAT prep works later. A steady block beats a frantic crunch.
Study your mistakes until you can teach them (the review move). This is the big one, and it’s the heart of how the LSAT gets beaten. Most students check which ones they got wrong, sigh, and move on. The points are in the move they skip: figuring out why you missed it. Not “the answer was C.” Why did B look right to you? What did you misread, assume, or skip? Write that down in a sentence, and the same mistake stops repeating. A chemistry problem set and an LSAT question reward the identical habit. The learning isn’t in the problems you do, it’s in the misses you dissect. (The full version of this, built for the test, is the Socratic Review Method in Anyone Can Beat the LSAT. You don’t need it yet. You need the habit now, on your coursework.)
Watch it beat the highlighter
Two students study for the same hard midterm.
The first rereads the chapter twice and highlights, four hours, feels ready, and gets a B-minus because the exam asked her to apply things she’d only recognized.
The second spends the same four hours differently. She does the practice problems with the answers covered, redoes every one she missed until she can explain the misstep out loud, and quizzes herself again two days later. Same time, but she gets an A, because she practiced producing exactly what the exam demanded. She also, without trying, just ran the LSAT’s core method on her chemistry. Four years of that and her prep later is a tune-up, not a rescue.
From the coaching file. Jordan was a grinder with mediocre grades, the worst combination, because he was working hard and getting little back. He didn’t have an effort problem. He reread everything and never tested himself. We changed one thing. Close the book, self-quiz, and keep a one-line log of every miss and why it happened. His study hours actually dropped, and his grades climbed almost a full letter in the courses where he ran it. Same brain, same hours or fewer, better number, plus a head start on the exact skill the LSAT pays for.
What a mistake log actually looks like
The review move is the highest-value habit in this chapter. So here’s how to run it, concretely. Keep one page per class, physical or digital, doesn’t matter. Every time you miss something, on a problem set, a quiz, a practice problem, write two lines: what the right answer was, and, more importantly, why you got it wrong. Not “careless,” because that word is where learning goes to die. Write the real reason: “I assumed the formula applied without checking the condition.” “I read ‘increase’ as ‘decrease.’” “I never actually learned this definition, I just recognized it.” Then, before the exam, you reread your own log and study your mistakes, not the whole chapter again.
Two things happen. First, patterns appear. You’ll see the same kind of error three times and realize it isn’t bad luck, it’s a fixable habit. Second, your studying gets ruthlessly efficient, because you stop reviewing what you already know and spend your time only on what trips you. This is the same engine as the Socratic Review Method that later moves an LSAT score, run here on your chemistry. The students who keep a real mistake log don’t just get better grades. They learn how to learn, which is the skill underneath every other skill in this book.
Do this now: this week
Take your hardest current class. For the next assignment or quiz, ban rereading. Instead, self-test from a blank page, redo anything you miss until you can explain the error in a sentence, and review it again a couple of days later. You’ll notice two things. It feels harder than highlighting, and you remember more. That discomfort is the feeling of actually learning, and it’s the same feeling you’ll want to chase when you prep for the test.
When you only have an hour
The honest objection to all this is time. So here’s the version for a busy week. If you’ve got one hour to study, spend zero of it rereading. Spend the first 40 minutes testing yourself, on practice problems, flashcards, or just shutting the book and writing what you remember, and the last 20 redoing what you got wrong until you can explain the miss. That’s it. An hour of recall and review beats three hours of highlighting. This isn’t a method for people with more time. It’s a method for people with less. The students who swear they don’t have time to study right have it backwards. They don’t have time to study the slow, useless way. Active recall and a quick mistake check are what you do precisely because the hour is short.
KEEP THESE 3
- Rereading and highlighting train recognition, which collapses under exam pressure. Production is the skill that scores, on finals and on the LSAT.
- Three moves do the work: test yourself, space it out, and study your misses until you can teach them.
- It’s one skill with two payoffs. Build it for your GPA now and you walk into LSAT prep already running the method that moves the score.
You’ve now got the full Number toolkit: protect it, pick a major you can win in, and study in the way that produces grades. Next we turn to the second move, the reasoning the LSAT and law school reward, starting with the most surprising advice in the book: don’t study for the LSAT yet.
