SAT CHEM HELP

Hi everyone! So I am really confused because I do not know if I should take SAT Bio or SAT Chem. I was thinking Bio because it is easier and I am good at memorizing, even though I hate bio. Chem because I love chem and I took high school Chem and General Chemistry, a college course and I did really well. Also I really want to become a Chemical Engineer so I feel like taking SAT chem would be so much better for colleges than bio. But the thing is I heard Chem is really hard. Is it possible to study Chem in like 2 months and get like a 750+? What books can I use for Chem and how should I study? Or should I just take Bio? Thanks!
