WJEC Remark and General IGCSE Question

Hey guys! So I just received my results a couple of days ago and am quite happy with the grades I achieved. I do have 2 questions about them though; Firstly, I did WJEC Film Studies and ended up a B - I was expecting an A in this and am thinking of a remark but there doesn't seem to be a way to get my mark or UMS! I have gotten the UMS for the rest of the subjects which I took which were in CIE, Edexcel and AQA and I have asked my film studies teacher for my marks but they don't have it either. If I really want to see how close I was to an A and think about a remark what should I do?

Also, my GCSE results were at 4A*'s, 2A's and 3B's. I know these aren't the best and I could have definitely got some more A's if I had studied more, but are they good enough for relatively good universities? (Not like Oxbridge or anything but still good universities)
