Practice full exam-style questions with linked parts. Answer each part and submit it on its own — every part is marked independently, so an earlier slip never costs you later marks. Written "explain" parts are checked for the key ideas NCEA looks for.
Entering answers: for very large or very
small values, use standard form — e.g. 1.6e-19 or 1.6×10⁻¹⁹. Plain numbers
(including whole numbers) are also accepted.
