### Teacher advice

If a student is aiming at European Olympiad of Experimental Science, point them towards the relevant national olympiad or selection body and help them prepare with past papers and extension work.

## How to prepare

- Work through past European Olympiad of Experimental Science papers or sample problems from the official site where available
- Build depth in biology beyond normal school specifications
- Practise under timed conditions and review full solutions carefully
- Follow the relevant UK national selection route rather than waiting for international registration to open
