getting better on the RW section but keep stuck at low 700s on the math section. any tips on the final push for december SAT? I'm aiming for a 1400 at the very least

was really struggling on RW section mod 2 and running out of time for the last 5 questions on math mod 2. my first attempt (prac 4) i only did the math practice with extended time i and i got a 770. so i guess my struggle in math sec 2 is timing. any tips for both issues (RW and math)?
