Am i overestimating myself?

I might actually have that

i know Cambridge and imperial dont consider GCSEs but what were your GCSEs

google impostor syndrome

but it doesn’t take a genius to realise that they will much prefer a 4 A level candidate than a 3 A level candidate.

My IGCSEs are 5 A*s and 1 A

I know people are sharing their opinions and some I note say 'experience', but I can only speak from our family experience.

Our son applied to Cambridge for 2015 entry, coming from a state school (comprehensive) that rarely sends students to Oxbridge. He applied with three A-Levels.

At the interview, he encountered people who were undertaking 4-A levels as well as many who were taking 3 A-Levels. He thought that they were 'all amazingly intelligent'.

He thought the interviews were tough and felt really pushed. He came out of his second one telling me that he had 'definitely flunked it'. I would suggest you look at @Doonesbury's analysis of whether there is a correlation between how people actually do in the interview and who is actually successful in getting an offer :-)

Much to our son's surprise, he got an offer and he matriculated in 2015 with his three A-Levels in hand. He graduated this year with a First.

Too many people get put off applying for Cambridge and Oxford because of myths that some people believe and continue to share. The reality of our experience is that there is no prejudice against state schools or applicants with three A-levels. They just want good students that they think will flourish in the Oxbridge learning environment.

From your original post, I understand you have already applied so you are over one of the major hurdles that people encounter with Oxbridge - they fail to apply in the first place.

...if you get an interview, try and enjoy the process and, if Cambridge is the right place for you, then the best of luck in getting an offer.

nobody is really likely to get into Cambridge but it's worth a shot for most applicants including you, having 3 A-Levels doesn't mean you won't still have a chance.

Imperial is more realistic (if your predicted are above or the same as their entry requirements). You just have to prepare for your interview.

Dont get me wrong i dont think the problem is the entry requirements but the fact that only actually genius people go to these universities..
