Hello! I´ve actually passed both BA1 and BA2, still to do BA3 and BA4.
The maths isn’t really that challenging – maybe a few questions on annuity repayments (interest + capital), and depreciation using logs that got me, but I think that’s just me not revising sufficiently. Enjoyed probability!
In the exams I tended to do all the questions which involved equations last, by that time you´re probably confident how things are going (at this level anyway)..
So don’t be put off by the maths, I´m sure you´ll be fine.
