I got 3A*s in maths physics and chemistry at gcse with 198/200 UMS in chemistry - I took those three at a levels, and let me tell you chemistry is something else. It’s dragged me to the floor along with all my other subjects, I lost all motivation for chemistry, in turn dragging the other two with it - at the start of the year I was determined for 3A*s - I’ve just finished my A2 levels, just a couple more to go and there’s no way I’m getting c’s - if you have any doubt that you won’t enjoy chemistry, you’re right and it will *uck you up big time.
