No offence mate, but what do you intend to do AFTER philosophy? It's all good and well studying a subject you love and are interested in, but after that? Philosophy is not in-demand, you will end up accumulating a debt that, well, wasn't worth accumulating in the process.
If you can, at least swap out Critical Thinking, and in its place, do something useful, aka STEM subjects (they are the most useful subjects like it or not, or the Russell Group's facilitated subjects. I'd advise doing A-level Maths if you can.
