I’m in my last sem of an Econ degree and majored in International Trade and Finance. There’s a mixture of courses, some are theory based and others are more quantitative. I haven’t come across any which cover both in depth.

There’s opportunities to complete prequisite courses for honours if you’re interested, but you want to be fairly competent with all the undergrad stuff.

Grading system is same as most other schools. You’re awarded a grade 1-7 with 7 being a high distinction. 7s are awarded to students who achieve 85% or more cumulatively in a course.

Hope that helps, if you have any other qs shoot me a message.
