The Russell Brand group and even Cambridge had outlined certain subjects that they assumed 'soft' and Accounting would, if my memory served me well, be in the list. The full list of the 'soft subjects' that would reduce your chances in future academic institutions internationally can be found through Google.. There's one pdf from Cambridge too.
I would totally advice you to take my rule. I called them the 'Traditional Three', 'Super Four' and 'Ultimate Five'. The traditional three would be Physics, Biology and Chemistry.. This traditional combinations would usually allow you to further to almost all courses, with exception to Mathematical-affliated courses. The super four would be the traditional three and Mathematics. This would open up every route possible. And, Ultimate Five would be the super four and any other non-traditional subjects, with preference to Further Mathematics.. This would definitely get you somewhere.
By the way, Accounting in lower level of education is not a vital pre-requisite, though it'll greatly boost your admission status.
