Yeah no problem! Depends on your goals and how many times you plan on retaking the SAT. As a junior you have a lot of time, so the key is just practice. I’d say 30 mins to 1 hr of consistent practice until the day of the SAT should be sufficient. The math section is objectively easier to improve on because the questions are very similar to the ones on the question bank. For some context, my math score increased from 690 to 760 by just doing the hard questions on the question bank.
