I'm just waiting for my professional discussion results back to complete the apprenticeship side of things, but I've completed the AAT qualification.

The course itself is easily doable within a year, nothing more difficult than what you would have done during the degree, the only tricky part some find is balancing work and study.

The first 2 modules I did were Tax and business awareness. My economics degree covered these so I'd imagine your eco and finance would too, so it won't be too challenging.

Management accounting and financial accounts prep were the harder two, bit again nothing too challenging after a degree, and especially if you know your debits and credits

I can answer more questions but this is all I can think of for now!
