knowledge of maths actually is not vip, but if you studied it in the past, it adds to understanding and speeds up coverage of relevant study sessions
though remembering/understanding how to differentiate is one thing that gives huge advantage in understanding option greeks in level II, otherwise you will have too learn the relationships.
and probability theory/statistics was extremely useful in level I quant staff. Again because otherwise it involves painful memorising.
Level II quant is more of econometrics stuff, which i studied before but didn’t remember a thing. But in the end it is again about memorising all those tests like DW.
If you take a big picture glance, quant in level II is only 5% and the time you sill spend on it is not nearly commensurate with the contribution to your overall score on the day of the exam.
