Again, you can only take the tests online, so you won’t necessarily get as much out of the experience.
There also aren’t any free-response questions, so you’ll have to look elsewhere (preferably the College Board website) if you want to practice them.
This means that you won’t have to put in quite as much legwork to see where your mistakes happened.
One drawback to the online format is that you can't directly replicate the conditions of the AP test.
It will probably take you less time to fill in your answers than it would on a pencil and paper test.
Kaplan Practice Tests Here you can find practice quizzes that cover all the different topics in the course as well as two comprehensive 100-question practice tests.

Be sure to intersperse official practice tests with these unofficial ones in your studying.
