I'd say Maths but that's compulsory, but apart from that Computer Science and R.E. - you just have to memorise and you'll do great.
English Literature is tough though, at least for me. I find it difficult to memorise all of the quotes and analyse, but that's because I'm a logical thinker (which is why I'm better at Maths, Computer Science, Physics, etc.) so making up potential meanings is what I struggle with. However, any subject that you enjoy should be relatively easy, or at least better in terms of understanding the content.
