How to practise for National Grid
- Sit each test timed - most assessments score accuracy first, then speed, so practising under the clock matters more than getting a perfect score untimed.
- Read the worked answer on every question, even the ones you got right, so you learn the fastest method rather than just the result.
- Create a free account if you want to save your scores and track your percentile trend across sessions - it stays free, with no card.
