Physics/Math2 advice, fast please!

Due to dearth of time, i had only 6 days to prep for physics and math2 (im giving them on may 2nd), and i ended up skipping the topics from my books and moving to the tests.

My scored are as follows:
Mean of 4 test (physics, from barrons) -62 Raw score (which is 780-800 i believe).
and a 63 from PR.

Math 2 - 760-780 from barrons (3 tests), test 4 being the only anomaly at 690, but i attribute that to a lack of sleep.

Ive skipped optics and magnetism from physics completely, with a large portion of light waves and stuff.

I have a basic understanding of those topics, but i havent covered them from barron ( i found the topic in barrons physics to be a bit off point imo).

Is this good enough to land an 800 in the actual test?

Also, is it just me or are 3D geometry and Conic Sections’ questions in barrons tests extrememly difficult at times?
