So I've been looking at the handbook for b science and it says that we have to do 144cp of subjects. However I've looked at my majors, prereqs, maths and all for the areas I want to study in and I've found that after putting those in they add up to 144cp however there are 2 other subjects that I really want to do I just want to know if were able to overload and do a few extra subjects than what is available
