If you are going to do the General Course next year, one thing that you will notice right away is that the grading scale here. Basically a 70+ is 1st, 60-69 is 2.1, 50-59 is a 2.2 and 40-49 is a 3rd. In essay-based classes, it is very difficult to get a first - you definitely should not expect a 90 because a 90 according to the grading scale is something that changes how the subject is thought of in the field - a groundbreaking work. I'm pretty sure that not many undergraduates (if any) have been able to produce such a work! In quantitative courses, it is much more possible to achieve a high score, but there is also a lower floor on you performance compared to an essay-based class. In math courses, homework is graded slightly differently, with performance ranging from Very good, good, satisfactory, pass, and fail. Since the homework sets for math classes tend to be fairly involved, it is difficult consistently getting a "very good" as well.
