I agree with leehuan, different schedules work for different people. The only important part is a strict study schedule and that you stick with it. For me its
3:25 - 6:00 Free time
6:00 - 7:00 Dinner
7:00 - 9:30 With a 15 minute break at 8:00, Studying material and completing work from the day, then if i finish that i start on reviewing my notes with the Cornell notes system.
Then on Weekends in the morning and evening I go through my notes and review all the notes from the Term, drilling them into my mind, and also reading around the subjects.
A Joke from my Chem teacher
Do it once: Atar - 50
Do it twice: Atar - 75
Do it three times: Atar - 99.95
The most important thing is consistency and sticking with it. In my schedule there is plenty of free time that i can expand into if i need to for more study.
lucky go don't go to an assessment based school then, you have so much free time.
For me its:
4-4:45 Free time (including getting home, changing, unpacking bag, eating a snack)
4:45- 7: Get all my homework, class tasks etc. done
7:00-7:15 Eat dinner
7:15-7:30 Shower
7:30-8:30 Piano practise
8:30- 9:00 "Family" time + prayers (is a nice break from schoolwork)
9:00-11:15 Study for upcoming assessments, (or if a submission, actually do the assessment)
11:15- 11:35(ish) Quickly type up notes from that day
11:35-11:45 The bathroom situation
11:45 Bed
been doing this (except notes) since year 10, cause my school made year 10 ultra hard
