Hello, for those of you who have used Chad’s Videos to prep for the OAT, is it important to fully understand every single chapter of Physics, Gen Chem and Orgo that he has posted on there? Or which chapters are not that relevant to the exam, that I wouls not have to worry about spending too much time on if I am not grasping the concept? Any other suggestions about using Chad’s Videos would be appreciated as well, thanks!
