Can I get some prep advice dudes?

Hello CC! I am a rising junior hoping to get a 4.0 straight A's next year. I know everyone on the planet has this goal but I really need this to increase my gpa from a 3.0uw. I also want to show colleges an extreme upwards trend. So here's my schedule

AP Lang (Joke class)
AP US
AP Physics 1-- (took regular physics freshmen year)

Chem Honors
Trig Honors
PLTW Electrical Engineering


So I was wondering how should I go about prepping for these courses to make sure I at least get a soild A for the first couple of weeks. I also need prep advice for SAT Math 2, physics, and chem. Thanks for your time!
