If you want a good score...learn the freaking material. If you're not serious...don't study it, take a chance, get a crap load of material you're weak on...then come back on this forum and complain/cry/ whine about how unfair the test is...
I think u should definitely get the Destroyer and read the answers in the Bio section, It really helped me to get 26 in bio. Don't memorize the questions but u definitely should memorize and understand the answers. Good Luck. http://www.d-e-f-i-n-i-t-e-l-y.com/
