Sat Subject Math Level 2 and Chem

I got the Barrons book for both of these tests and scored a 650 on the Sat Math level 2. On Chem, I got a 800, 740, 760, and 750. What are my chances of getting an 800 on both of them?
I’m screwed for math. anyway soo

Well since Barron’s is supposedly harder than the Sat II itself, I believe getting 600+ is getting 750+ or even a 800. If you don’t mind, when did you start prepping for Sat II Chem (like after regular Chem or AP Chem)?

I started prepping after AP Chem

Ah, the reason is that I also want to take it after I’m done with regular Chem.
