I enjoyed them- I'd probably do the same subjects again if I could go back. I found Spanish to be the subject with the highest workload (probably more than the others put together in terms of the amount of independent work you were expected to/needed to do) and I dropped it at AS but I'm still glad I did it. It was nice to have a bit of a contrast to the sciences I loved Chemistry at AS but it got a lot harder at A2 IMO, and Biology was v.interesting but I had to do a lot of revision for it because there was a high volume of facts and processes to learn whereas Chemistry was more understanding things and applying them. Maths was my favourite subject and the one I found easiest to practice and revise for
Good luck
Oh right, at the moment, Spanish is my favourite out of the four of them! Thank you!
