(ii) The magnetic domains of magnetic materials are aligned either parallel or antiparallel arrangements thus they can respond to a magnetic field when they are under the influence of an external magnetic field WHILE The magnetic domains of non-magnetic materials are arranged in a random manner in such a way that the magnetic moments of these domains are cancelled out. Thus, they do not respond to a magnetic field.

WAEC Physics Past Questions | FREE DOWNLOAD

WAEC Physics Questions – Free WASSCE past questions for Physics.

Here is collection of Physics past examination questions to assist you with your studies for the West African Senior School Certificate Examination (WASSCE) for both School and GCE candidates.

If you are in your last stage of Secondary School Education (May/June) or not in the School system (GCE), the importance of using old exam papers in preparing for your West African Senior School Certificate Examination (WASSCE), cannot be over emphasised. By using past exam papers as part of your preparation, you can find out what you already know. By the same token you also find out what you do not know well enough or don’t know at all.

See: WAEC Timetable for May/June Candidates and WAEC Timetable for GCE Candidates .

What is more, the WAEC past questions for Physics can also be used as an organisational tool to manage your time better, as you can plan according to each section of the paper.

As a matter of fact, revision is more better than memorising facts and going over notes. You can practise for your  Physics WAEC Exam by answering real questions from past papers. This will give you a better chance of passing.

WAEC Past Questions for Physics

Click on the year you want to start your revision.

• Physics Paper 2 (Objective and Essay) – November 2011

Do you have any other past question(s) other than the ones listed here? If yes, don’t hesitate to share them with others by sending it to  [email protected] .

Physics (Essay) Paper 2 WASSCE (SC), 2023

• Subject Home

General Comments

The quality of this year's exam paper was impressive, with appropriate items and clear, unambiguous questions that fell within the scope of the syllabus. The paper also included well-reflected operational and graphical cases, and rubrics were provided clearly. Additionally, the allotted time for the exam was sufficient.

However, there was a significant decline in performance compared to the WASSCE for School Candidates 2022 examination, with only 846,875 candidates taking the exam and achieving a raw mean score of 19 out of 60, and a standard deviation of 09.00. In contrast, the 2022 exam had 801,212 candidates and a raw mean score of 25 out of 60, with a standard deviation of 10.15.
