What Maths Skills should I brush up on?

Hi,

In September I will be starting a maths and physics course and was wondering if anyone has any suggestions what maths skills should i review for a better understanding. I'm from the Scottish Education system and i sat Higher Maths in the 24/25 academic year so it has been a while since I reviewed polynomials, optimisation, logs and exponentials in great detail. So does anyone have any ideas?
