how do you make the best use of DAT destroyer? especially in the biology? Do you just do the question and look up the answer key? What else do you do to get the most from using DAT destroyer? thanks

First do the question and figure out wat u think the answer is.
Then look at the answer and read the explaination, even if u got the answer right. Theres a lot more information in the explaination than the questions itself. So know the questions and the explaination word for word. If u can do that than ur good to go.
