The grading system depends on the university. Some give A-F grades; others use a scale from 1-20 or 1-22.
Most students tend not to have too many graded assignments. It’s common to have the grade for the semester based upon one or two papers and a final exam.
Many courses will have one day of lecture a week and one day of tutorial a week. Tutorials are held in a smaller group and are discussion-based. Sometimes tutorials are taught by postgraduate students instead of professors.
