Do retaking the GCE exams hurts your chances at getting to a good university?

[ArifKhan]

I know this might be a silly question, but if you retake the GCE exams privately, does it hurt your chances at getting into a good university?

I was told once that you could selectively choose which scores to send universities so they would never know you retook the exam more than once. Is this still true or is it now mandatory to tell universities how many times you took this particular O/A level exam?

If this all sounds incoherent, let me break it down:

1. Is it mandatory to tell American or British universities how many times you retook a private GCE O/A Level exam?

I would really appreciate your advice when it comes to this question. Apologies for double-posting.

Reappearing won't effect your chances of getting into a university provided that you don't send them your previous results.
Any average university in the world will have more than 10000 applicants or so per year. Do you really think that they've got enough time to check the number of sittings of each individual applicant? I don't think so
