In my opinion, yes Cambridge is a good university, but it is massively overhyped
I for one regret coming- and thats not to say you will too, I just want to help prospective students get this university into perspective
The fact that it will be massively useful in the ever- tightening job market consoles me- but I don't think its a good thing that oxbridge degrees are set on a pedestal that way- I don't think its always necessarily the absolute best course in every subject, and even if it maybe is, it isn't necessarily the best thing for you
St. Andrews is up there with the Russel group- all right behind oxbridge, and in my personal opinion, they are probably a lot more fun. St. Andrews and Cambridge are both extremely small, so I just mention that because its a problem for me personally (but the crowd is what makes a place fun)...
As far as I know, East Anglia isn't quite up there... but ask other people for their opinion...
if you really think cambridge is right for you for the right reasons (ie not because you just visited it and was overawed, and you have this picture in your mind about 'omg its cambridge!!'- because I was one of those cringing 17-year olds who idolised oxbridge, and once I got there- I found out that basically- reality is reality, and it has its ups and downs everywhere...)
it is worth considering that history or art isn't the most in demand on the job market- I know degrees are not all about money and careers, but you don't want to be struggling and confined in life 5 or 10 years down the line because of your degree- it is important to look at a degree as an investment, and remember that 3 years seems like an age at 19/20, but it isn't as long as your life afterwards...
if you are in school right now OP, certainly do reapply if you want to - I strongly believe that students should really take a gap year before uni- I think its the best thing for the majority of people- and I strongly feel that it shows in cambridge students when all they've ever known is school, and life with their parents and childhood friends (often in a cosy, small english town or city)- my gap year really helped me learn what I really want in life, before, I had no idea (I didn't realise at the time)... so in my opinion, you will more likely end up choosing a uni you will enjoy
it does sound like you aren't that kean on St. Andrews (and if you feel that way now, you could well get sick of such a small town- its all the way up in scotland, its near-ish to edingburgh but not that near, and it is tiny)...
my verdict is- reapply
but don't be set on cambridge- reapply if you seriously have thought through why you personally would like it (because- take it from me- that is crucial!) and apply to other unis in the AAA*-AAB bracket which sound good to you, and where the course appeals to you, and do something brilliant and exciting on your gap year (I am so jealous that you might have 15 months to plan exciting things- I wish I had that again so I could travel or get experience and skills working...!)
message me if you have any questions
good luck OP
