best prep books for physics.

What is the best prep book for the physcis subject test?
I took physics last year so i’m going to need this book to review the main concepts.
also we didn’t do much electricity so it needs to have good explanations on that.
But probably the most important thing is to have accurate practice tests because if it really comes down to it I can use the internet to review all of the material.

is self bumping a thing?

A combination of Princeton Review and Barrons is best, but if I you want just one, go for PR because of its accurate practice tests.
