Admissions tests are one of the most important and often underestimated parts of the UK university application process.

For competitive universities and courses, particularly Oxford, Cambridge, Medicine, Law, and STEM subjects, admissions tests are often the deciding factor in whether a student progresses to interview or receives an offer. Strong grades alone are rarely enough.

This guide explains which tests you may need to take, why they matter, and how to prepare effectively.

If you're an IB student, or the parent of one, understanding how IB grades are calculated and what universities actually look for is essential. The IB Diploma is one of the most rigorous pre-university qualifications in the world, recognised by leading institutions across the UK, US, and beyond. But the grading system can feel opaque, especially when university offers are expressed not just as a total score, but with specific Higher Level requirements and core component expectations.

This guide breaks down everything you need to know: how the 45-point scoring system works, what counts as a competitive score for different types of universities, why your choice of Higher Level subjects matters as much as your total points, and what to do if your results don't go as planned.

Whether you're just starting the Diploma Programme and planning your subject choices, or you're approaching results day and trying to understand where you stand, this article will give you the clarity you need to make informed decisions about your IB journey and your university application.

Biology admissions are more competitive than ever, with top universities like Oxford, Cambridge, and Imperial accepting only a small percentage of applicants. Oxford received 731 applications for Biology in the 2024/25 admissions cycle and accepted only 109 undergraduates, a success rate of only 15%. Cambridge's Natural Sciences programme had an acceptance rate of 22% in 2024/25, accepting only 569 undergraduates from 2,529 applicants.

The difference between successful and unsuccessful applications lies in demonstrating genuine intellectual curiosity through biological exploration using specific experimental or research examples, rather than generic statements about biology being fascinating or life-saving. Students who secure places on leading biology programmes show admissions tutors they're already thinking like biologists: analytically, experimentally, and with deep appreciation for molecular mechanisms, evolutionary principles, and the complexity of living systems.
