Just sort of hijacking the finance 1 discussion, do I have to do finance 1 to major in finance? I think there's another pathway if you do QM1 and IFA but I'm not sure, I emailed the student centre but they didn't reply 
Yep it's fine to do qm1 and ifa to get into business finance. That said, if you want to major in finance it is probably good to get an introduction to it in first year? That way if you absolutely hate it you will still have all your options open. There are also second year finance subjects that you can enter with either business finance or finance 1 as a prereq, so which pathway you decide will affect the subjects you can do later on (but busfi alone will get you into enough 3rd year subjects for the major).
For what it's worth, I didn't do finance 1 and didn't feel disadvantaged in business finance seeing as it's taught from scratch. However I had covered all the financial maths stuff in other subjects so I'm not sure what the pace feels like if you haven't seen it before.
