Daniel Merrett, 17, a student at a state school in Portsmouth who was on free school meals, has an A in maths and is predicted AAA in further maths, physics and computer science. But he was rejected by his four top choices of Oxford, Imperial College, Warwick and Bath. He received the decisions very late in the cycle and has decided to reapply next year rather than take up his insurance offer from Liverpool*
But this is the issue. Assuming he is applying for Maths, or CompSci, these four universities are the most popular for those courses, every, single, student will have four A*, and they have thousands of applicants. It's like Oxbridge, you only have a one in four chance of getting in, if all of your other choices are also only one in four, or less, then the odds are against you, even in normal years.
