The problem with OAT destroyer is the practice questions are scattered all over. I wish the questions were laid out and organized by topic for each subject. I need a resource like that. As I study with kaplan + chads videos, there isn't much practice questions for each topic I study.
For example, as I studied Molecular Geometry today with kaplan and chads videos, i needed questions to practice and didn't have any. Kaplan had subject tests but those are cumulative and to be taken after a lot of chapters of studying. Chads videos has small mini quizzes, i did those, but I need more. OAT destroyer is awesome, but questions are so scattered, like random - Like question one will be about hybridization and question 2 about thermochem, when I haven't even started thermchem.
