I'd really appreciate a comment. My situation is such that I have accepted three unconditional offers for my masters, and finally decided where I want to go (my choice was the last to get back to me), now I want to send a polite letter rejecting the other two courses. My reasoning however is not financial but due to the course. Should I say it is financial (which it isn't), or should I say something like after much consideration I have decided the course is not for me (and leave my reasoning ambiguous), or should I say I've chosen another course which to me reflects very badly on me and I'm slightly concerned as I may well want to go a conference at that uni or maybe apply for a phd in the future. Please any thoughts.
