I really loved my A levels, I did a combined English lang-lit A level, with music and RE. Loved them all!
However, I'm now doing an English language degree, and if i could go back and pick different subjects, I probably would have!
I had two lessons of A level French, and decided not to stick with it, but I wish I had now! Also, doing sociology, or law or psychology would have been much more useful than RE or music, but hey ho!
I have no regrets!!
