Radioactive waste

A-level exam papers include questions that require an extended written answer, such as this one on handling radioactive waste

Facing an extended-answer question on an exam paper can be intimidating — a large empty space needs filling with words, and a significant number of marks are available. However, these questions can be approached in a systematic manner and, provided you do not skip over essential details, the space is easily filled.

Examiners like extended-answer questions because they test a different range of skills from questions based on calculations. Most students fare well on numerical questions, perhaps because they have been given ample opportunity to practise calculations. However, even good students sometimes struggle to write coherent passages to explain their understanding. By setting extended-answer questions, examiners can ensure that the exam paper provides a broad range of marks, helping to distinguish between students of different ability.
