First off, congratulations for those who got into Cambridge!
I'd like to share some information here that may be helpful for international students in particular. Prodigy Finance is a loan provider that specifically funds students who are travelling abroad for their MBAs, and they don't require a co-signer. Check it out, as it might be an option for you.
Unfortunately, they do not cover the Mphil programs in Judge...Otherwise, it would be an easy decision for me.
