I have to agree with @iliketeeth1995. I'm a super strong advocate for the Destroyer--I owe it and the Math Destroyer my life for my scores. Please do not use BC as an indication of how you will score on test day. If you don't have the concepts down, which the Destroyers DEFINITELY hammer into your head, you're on track to have a bad time come test day. Those foundations are incredibly important, and the Destroyer gets those down plus some.
I personally went through both the general and Math Destroyers at least two times through each section to get those questions and concepts drilled into my head. Trying to get representative questions for the exam will get you nowhere really, because no one can predict what you will see on the exam. The concepts are what you need, and the Destroyers will get those down.
I highly recommend Dr. Romano's Biology notes as well. They cover everything you need to know for BIO and more. Plus, all of this will save you money going forward. If you have any specific questions, please let me know--I'd be glad to help. My breakdown has my description of how I utilized all of these resources if you think you would find it useful.
