Sat Chem and Sat Math Level 2

On the Sat Chem test, what are some colors of elemental compounds that you have to know. Do you have to also now about falme colors, the different preparations of compounds as well. Also on Sat Math Level 2, most of the questions are really vague and obscurely difficult but I still manage to get a 770 my second time around. I also got an 800 on the practice Sat chem test. Could I get an 800 on both tests if I keep up this pace?
