Honestly Maths is just like this. However, If you enjoy geography more, then you should probably do Geography because you don’t actually have to do Maths for most sciencey courses. They have maths lessons at uni for people who didn’t take Maths A Level and Geography is a very good A Level to take for getting into variety of degrees. But if you’re gonna stick to Maths, then just to let you know it is hard work for the whole two years but if you work hard, you’ll get a good grade out of it and it will still be a good a level to do for preparing you for uni.
