Whereas I dropped out of school at 17 after being on track to fail my A Level in Maths and yet I recently built an ERP system for a $100m revenue company. No one checked my (lack of) qualifications! (Nor did my lacking certain bits of paper impede my ability to do a good job)
I’m not as bad at maths as that failed A Level would have indicated, but I doubt I would have easily sailed through accountancy training/qualifications. Not for lack of intelligence but for lacking in other areas.
So raw “math ability” is only one element here and just focussing on that could risk minimising all the other skills required to be a good accountant (including organisation and people skills).
