Hey. I don’t have much information about the course, but I can give you my 2cents about the price of London. You are indeed correct that it is expensive here. I highly suggest you research student Maintenance loan and see if your eligible for that. If not, they are still ways to make money here in London. Before coronavirus, you could legit get a job within a week in hospitality. Working agency shifts let’s you be flexible with the days you work and you can earn about £9 or £10 an hour (which is above the minimum wage)
My personal experience, I was being paid £13 an hour from an agency called “the change group”. However, since coronavirus hit London, jobs have dwindled to nothing. But once we are lifted out of lockdown and hospitality opens back up, I suggest you have a look at ‘The change group’ and see if you can do some bar work or a waiter. Of course you’ll need a work visa to do this so I’m not sure if that’s something you already have. I hope this helps, if you got any questions about work, let me know
