I was doing the subject tests as kaplan had in the syllabus but then i realized that some of the subject tests covered material we hadn't covered yet in class. So i decided to do the subject tests for each subject after i am done reviewing all the content (which will be by the end of this week). But for the subject tests i have done (Physics, chem and ochem 1 and 2) they are really good...except for the physics ones they are extremely hard
