Make a timetable of your subjects to be studied.
Keep to the timetable! If you don’t you probably won’t catch up on the backlog.
Decide on the best time of the day for you to study.
Recognize your “biological clock” – if you work best in the early part of the day, plan to finish work early enough for a good rest.
Don’t be tricked into waiting until “you are in the mood”
Most of us never are.
