hey,
so i've done a bunch of gen chem exam krackers problems and theyre pretty useful i think, i mean i wouldn't know because i have yet to take the actual DAT but i think they were better than kaplans. Kaplan seems to have lenghty problems that i think on the real DAT would be too time consuming. With EK i think theyre more direct? thats just my take. I only studied EK because i had the books at my house already since one of my siblings used them for med school but if you dont have the books, i wouldn't necessarily purchase it.
I also find DAT destroyer and EK to be very very similar in question type.
Both are fairly difficult and really test your knowledge of the material
