Welcome to our school exams series, where we provide students with well-structured termly examination questions and answers. In this post, we’ll focus on JSS2 Basic Technology Objective Questions for First Term. These questions are designed according to the Nigerian curriculum to help students test their understanding of key topics and prepare effectively for both school and BECE examinations.

Basic Technology in JSS2 builds upon the foundation from JSS1 by introducing learners to more advanced topics in engineering, mechanics, and technical drawing. Students explore areas such as energy conversion, maintenance of tools and machines, woodwork processes, building construction, and electrical systems. The subject helps to develop creativity, innovation, and practical problem-solving skills needed for technical education and real-life applications.
