How many hours should I study per week in order to get good grades?
The general rule of thumb is to study 2-3 hours for every hour you spend in lecture (not lab or tutorial.) For example, if you spend ten hours a week in class, expect to put in another twenty to thirty hours reviewing your notes, doing your readings, working on assignments, etc. It may seem like a lot but putting in enough time is crucial if you want to master your course material.
