What a good study schedule looks like
Good plans have three phases. Learn each topic first, then do practice problems topic by topic, and finish with mixed review and a timed mock exam a couple of days before, so you still have time to fix what you got wrong.
The day before the exam stays light: summaries and formulas only, and a good night's sleep. It does more for your grade than one more late night.
Stick to it
Use the Pomodoro study timer for each session and keep an exam countdown open so the date stays real.
