For the gen chem videos from Chad, what is the difference between the regular version and the DAT version. They are different in total length and names of certain videos. What about the content and the quizs?
CHAD Chem is for college chemistry and college organic chemistry.
Both are useful =) but CHAD Chem may be a little more specific than what the DAT may ask. However, I found the college chemistry series useful to further my understanding on certain topics that I was weak in or felt the CHAD DAT wasn't enough.
