I want to apply to Cambridge this year, but my chances aren’t so good, so I want to take an in-between year to improve my grades drastically and extend on my extra curricular activities.
But I am curious if I will receive an offer or not this year, so I would like to apply this year. If I do get rejected, and take a year to fix everything, then apply again- would that affect my chances of getting in?
Cambridge does not look fondly on resitting exams or taking longer than normal to complete courses.
You can reapply if you get rejected and you may be successful the second time, but resitting exams to improve your grades will probably work against you.
Other than that, having applied once already will not affect you, because all information about applicants is destroyed at the end of the admissions cycle.
From your other thread you are predicted AAA at A level, and I am not aware of any Cambridge course that would accept a student without at least 1 A* (doesn’t mean there aren’t any of course, I just don’t know which ones they would be). If you are applying with predictions below the usual offer, without some extraordinary extenuating circumstances you chances are just ‘not so good’, they are infinitesimally small.
