in first year there was one module which was basically just like a level but a little bit more advanced. We did titrations and stuff in the practical classes.
in second year i'd say its about a third chemistry. But its not so much like organic chem where you have to do all the molecules and stuff, its like analytical and phamraceutical stuff - obviously with a little bit of organic thrown in there. Lots of practical work which you have to write up which is a bit challenging. but then theres quite easy bits where you have to just learn about how to make tablets and machinery stuff. nothing too taxing there!! Physical chemistry was the main bit i struggled with.
I have no idea what third and fourth year will bring.
I only got a C in a level chemistry and I am finding it alright. So I'm sure if youre worried you wont be able to cope then you will. I even got an A in the chemistry module summer exam!
