When I decided to take AP Psychology in 9th grade, I had no tutor, no AP class, no academy, and no fancy online course.

Just one book, a pen, and the promise that if I read that book enough times, it would eventually stick.

It worked — I got a 5.

Here’s exactly how I did it and how you can do the same.

📚 The Only Book I Used

Barron’s AP Psychology — any edition works.

Barron’s and Princeton Review barely change their content unless the exam format itself changes.

If you can’t get the newest version quickly, buy a used one. It’ll be fine.

I lent my copy to a friend after the exam, so I don’t even have a photo of it anymore — but trust me, it’s all you need.

💡 My Core Study Philosophy

I’ve always believed one thing:

“Reading one book ten times is better than reading ten books once.”

AP Psychology proved that true.

You don’t need multiple prep books.

You just need one — but you need to absolutely master it.

So my rule was simple:

One book. Ten passes. Total memorization.
