<p>I agree with everything cupcake says. Also, quite recently Cambridge released a new admissions policy which explicitly states that under-18s will only be admitted in “special cases” - with deferred admission the likely result. You can find the policy here: [2.2</a> Mature applicants and under 18s: Cambridge Admissions Office: Undergraduate Admissions Handbook 2012-13](<a href=“Cambridge Admissions Office |”>Cambridge Admissions Office |)</p>
<p>Oxford doesn’t have an age policy as far as I know.</p>
<p>You may want to contact the colleges you’re interested in and ask about accommodation.</p>
