I have a pretty biased opinion, to be honest as I have loved English and achieved well in it since secondary school. However, I won’t fault maths. If you can understand it well and it’s a work type fits for you then go ahead. English Language, personally my favorite, would mean that you would need large amounts of time to go over your notes, analyze texts and create essays, articles or creative pieces out of them. Literature would take a large amount of your time reading. You would be expected to know all the quotations you will need for the exam plus background knowledge. Really both English subjects will take up a large margin of time, and both have a lot of differences from what they were a lower level You would need to look over all three in comparison to you other choices or subjects you have studied and decide whether you would have enough time to commit to the subject and also if it's right for you.
