Are my subjects too ‘soft’ are therefore looked down by universities Watch
Those are perfectly fine for what you are applying for. Cambridge in particular is usually relatively unfussy about what subjects you take when applying for the social sciences (within reason, coughgeneralstudiescough).
I keep on reading articles saying law is a ‘pointless’ subject looked down on by universities
Law is a solid essay based subject and not 'looked down on' at all.
Read this article from one of the exam boards - even Cambridge doesn't have a problem with it- https://media2.aqa.org.uk/content/news/2014-04-15/AQA-W-A-LEVEL-LAW-SUPPORT.PDF
Ah yes, that perception is based on information almost a decade old. When I applied (2010), law was a very maligned subject because it was new and generally horribly structured and taught. It was true at that point that top universities told you not to take it at open days. However, that is no longer the perception at all as the problems were fixed somewhere along the line. Unfortunately the rumour mill has not caught up.
I went to Cambridge and did the law BA there. My A-levels were English Language, Maths, Chemistry and History. I didn't know anyone who did the law A-level at the time, because as I say it was maligned when it first came out. That said, I knew lots of people who did sociology and English lit.
