Exam Structure and Marking Scheme

The NECO Physics exam consists of three papers:

Paper I – Practical (50 Marks, 2 Hours)

This paper tests the candidate’s ability to perform physical experiments, take accurate readings, record observations, analyze data, and interpret results. Typical questions include:

Measurement of current, voltage, and resistance
Determining acceleration due to gravity
Using a pendulum to find time period
Measurement using metre rule, Vernier caliper, or micrometer screw gauge

Paper II – Essay (100 Marks, 2 Hours)

This theory paper is divided into:

Section A: Ten compulsory short-structured questions covering a wide range of topics (25 marks)
Section B: Four essay questions out of which candidates are to answer three (75 marks)

Questions demand detailed explanation, derivation of formulae, calculations, and application of concepts to real-life situations.

Paper III – Objective (50 Marks, 1 Hour)

This section consists of 50 multiple-choice questions assessing understanding across the entire syllabus. Topics range from mechanics and electricity to optics and modern physics.
