Hi! What I'm going to say are all opinion and not based on any ''fact'' as such, but are from my experiences
Theres very little jobs in Psychology unless you want to be in schools, councilling or a therapist. If one of these interests you this could work at uni, if not I wouldn't persue this any further
There are loads of ethnic groups in the financing world! So do not let this fact put you off. The hours are long on the university course, however any high level dissertation based subject will be the same and you should be prepared for this going into any uni course - its not all just partying and getting drunk! (not after first year anyway...)
Are you sure you want to persue university at all? It's perfectly okay not to do university (either for a year or two, or even not at all!). People hype up university to be this big thing guarenteeing a job but employers many times look at your skills and experiences moreso than a degree. Have you thought about taking a year out and working full time in a financial / other employment setting? Or getting an apprenticeship or day release course from a company specialising in something you're interested in near you?
University is 3-4 years of your life and around £50,000 - do the benefits suit you?
You may find that university is definitely for you - in that case I really implore you to go to university open days and look and several courses - even ones you may not at first think are your thing! It's okay to have a gap year too to stop you rushing into it
