Chances of getting into Cambridge for a PhD (specific case - international)

Age and nationality are irrelevant, although nationality may matter for some funding agencies. How are you doing in your course? If you are doing fairly well (preferably on track for a first) in your course, you will probably have a decent shot as long as you have a solid research proposal.

Hi

I'm new to TSR, so hopefully I am posting this correctly. Basically, what are my chances of getting into Cambridge for a PhD, given the following:

I am an international student from Ireland, going to a university with a 5 star QS ranking.

I am currently studying a Bsc in Biotechnology, which is a four year undergrad course.

I have done ok in my state exams and got my first choice Uni application (our system is different to the UK), but I studied 7 subjects at higher level ( almost equivalent to A level standard).

I have a very strong track record in science competitions (came 2nd out of 2000) and since that:

I was sponsored to attend the London International Youth Science Forum (held in Imperial), and am setting up my own medical device company, which is supported by national organisations.

I entered a research communications competition in my university and won in my first semester of uni, even though I was the only undergrad to enter (postdocs and lecturers mainly).

I am heavily involved in science outreach in the university, and have done 2 summers relevant work and have gotten a summer placement in a lab this year also.

Basically, from the above, given that I'm still only 17, if I keep going will I be in with a decent chance? Will the fact that I'm an international student go against me? Any help/advice/guidance is greatly appreciated thanks so much!!
