I havent done three mid years, but heres my take;
if you study consistently, three mid years will not feel be hard to cope with + much easier than end of years = 5 exams+ (although spread out)
in midyears, you have to cover only 1 unit, WHICH will also
alleviate any pressure for end of years - a further one unit.
For accounting, unit 4 is literally 6 chapters, you can finish the whole course within a week without going 'all out'
as luffy said, dont do a subject you do not enjoy, you'll just hate it completely..
look at the psych course, the types of questions asked on exams and see if you enjoy that sorta stuff
Don't do a business subject if you don't enjoy them, it will just come back to bite you in the arse at end of years.

its just the trap most people fall into (or maybe just me)
Slacking term 1,
realising ur mistake a few weeks in term 2, and cram cram cram.
