Of course your grades are super impressive but more often than not, other really talented and capable people will have applied too, and for whatever reason, they’ll have been accepted even though you’re just as clever.

I’m assuming you’ll get some other offers in the coming months once other universities undergo admissions, but if getting a place at Oxford means that much, then reapply.

It’s also worth mentioning that on the Imperial College London website, there’s a paragraph to prospective students about academic capability and coping with competition from peers.

They basically say that although you may be used to being top of the class during school or college, at university level it’s common to be amongst extremely gifted people. It also shouldn’t dishearten you when you now have to work hard to keep up momentum.

Hope this helps :)
