How important is it to balance the credits between the 2 semesters? I want to choose a 10 credit module for the Autumn semester, but that would mean I do 75 credits in Autumn and 45 in Spring. Is this too much work for Autumn? Alternatively, I could do all my optional modules in Spring, but I'd have to pick a less appealing module. In the second case, it would be a 65/55 split.
Sometimes there are restrictions on how many credits you can take per semester - the aim is for a balance so that students dont get overloaded - so best to check if there are any regs at your uni about this.
