If you enjoy Maths I would definitely encourage you to take it as one of your options. If you know that your uni course doesn’t need it but does need certain subjects, I would advise you to prioritise the subjects you definitely need, but if you have options left over, maths is a great choice.
There is a lot of differentiation and integration (the reverse of differentiation) and you also use logarithms in the statistics section at points. The mechanics also has applied differentiation and integration so I think you’ll enjoy these sections too.
Good luck!
