Is university worth the debt? Watch
I'm dubious about this. If graduates are the beneficiaries they also pay higher amounts of tax apart from student loans - both at marginal rates and absolute values. My concern is not so much the morality as the impact of higher tax rates. Paying 50% of what you earn is a hell of a disincentive to save for additional training, move for a promotion or progression opportunity, benefit from a bonus.
Edited to add - all major parties are making noises about raising income tax to pay for the NHS (which is a code for adverse demographics).
London uni - UCL
Local uni - Cardiff
I could get a scholarship from Cardiff of £3000
However for London I’ll be receiving a maintenance loan from sfe wales of around 11,500 per year (about 3000 of this would be a grant so I’d have to repay around 8500 of it from each year). That should cover the majority of it but I also plan on working during the summer holidays / or even term time if need be.
There isn't really a right answer because this is your life. Obviously any advice you get could be very helpful, but be sure to make your final decision for you. It might help to make a bit of a pros and cons list and think about which of those means most to you. For instance the staying home option might be the best option financially, but if you would want to experience uni life more or would find your family distracting it might not be the best option for you personally. Likewise reputation of unis can matter a lot for some jobs and very little for others so there's not one solid right option there.
This is your life and you should live it your way. Especially since you'll be lining it for a long time still. You don't want to work out when you're 35 and pretty stuck in a role that you've been preparing for a life you don't want to live. Do future you a favour and think of yourself and what you want.
