SAT Subject Test Math2, Physics as IB Student

<p>Hey guys, I'm a junior taking full DP courses.
It's pretty weird, but i take Physics HL and Math SL.
It's because i was the only one who was willing to take Math HL at my school and im not that great with math.
I got only 740 in SAT1 for math section.
Anyways, my question is, when should i take the subject tests for physics and Math level 2?
Is physics HL and Math SL enough to get me 800 or do i have to do extra self study?
Thanks.</p>
