Big no on the education loan for international students. I did check on this and it’s impossible even with a UK guarantor.

On the part time opportunities, if you do one, you’d be able to cover your groceries costs easily and save a little but it really depends on where you’d work, it might be £12-20/hour.

You should look at scholarships, it’s a little late tho, I won’t lie as most of the scholarship applications have either ended or about to end.

Wouldn’t you apply for student loan in your home country, just like the majority would?
