Hey, I had a 3.3 undergrad and a 29 MCAT and lots of volunteering. I chose the GSP program because I would love to study in the UK! I love to travel and would like the experience.
As for your concerns, this is what I have heard/learned: Newcastle is one of the cheapest cities in the UK, a bunch of people on here have said that it is cheaper than Grenada for a lot of things. The programs are the same, and we will have access to the professors for questions and help, but I don't know about tutors. I figured that one year of private loans would be okay, most of the current GSP students went through Ed Invest and got full funding, and that is where I applied for my loan - no way could I go without loans!!! Hope that helps!
