Computer Studies – SS1, SS2 & SS3 Curriculum; Scheme of Work; Assessment Tests

Hello and welcome!

ASSURE Educational Services has put-together the scheme of work on Computer Studies  – SS1, SS2 and SS3 based on the National Curriculum and the syllabus of WAEC and NECO. All the topics highlighted in the National Curriculum and the syllabus of WAEC and NECO have been accommodated in our Scheme of Work.

End of term Assessment Tests in SS1, SS2 and SS3 alongside Overall Assessment Tests are available. Schools may adopt our scheme of work because of its simplicity and ease of monitoring of academic activities.

The Scheme of Work stated below is inexhaustible. Schools are encouraged to input weeks and periods of completion of topics in accordance with the academic calendar, number of students and available classes.
