You will struggle with bio for a while. I thought the bio and reading sections of dat qvault were a great supplement to the destroyer and dat bootcamp. It teaches you a lot but there are some realllly random stuff in there that I had not seen anywhere else. If its not in faralis notes its not relevant. Anyway, go through destroyer bio twice while making flashcards and if you still have time then go through bootcamp bio and if you still have time after that then go theough qvault bio. Just my opinion.
