What board are yo doing?
If it is AQA, go for it. I am terrible at maths, didnt do it at AS/A2 level but did chemistry and got a good A grade at AS and A2. There is bearly any maths. The maths kicks in at A2, but it is using log to calculate PH's and its really simple and just a few steps that you learn and repeat.
The most mathsy part of AQA chem a level I would say would be adding up MRs .. which is easy .. just add them. At A2 maths does get involved with rates and Ph, but it really isnt hard maths.
If you like chemistry, do chemistry.
