AAT Professional - L4 - College or Home Study?

I home study. I have passed the budgeting, financial statements, and decision and control exams. Just awaiting results of the synoptic exam (which I am dreading). For me, home study has worked really well, it also helps build a mindset of answering your own questions rather that relying on someone else. You do have to be very motivated but it becomes easier once you get into a routine. I have an exam every 3 months, study 3 hours a day (lunch break and after work) Mon-Thu and every other weekend (give or take). If you're funding studies yourself it's also the cheapest option.

Budgeting, financial statements, decision and control. But with what I know now, I'd do: financial statements, budgeting, decision and control, in order of relevance to the synoptic exam (least relevant first) so to keep the more relevant subjects fresher in your mind for the synoptic

There's also a guide on the Kaplan website I think with the suggested order for the units. Hopefully by the time you sit the synoptic they will have refined the exam a bit
