Questions

Which syllabus does this Strength of Materials course follow?

It follows the BTEUP diploma syllabus (Mechanical Engineering - Semester 3). If your polytechnic or university syllabus differs, the centre follows your own syllabus and unit order.

Will this help in the semester exam?

Yes. Each unit is taught with board-pattern questions, numericals where needed, and revision tests before the end-semester exam.

Are notes and tests provided?

Yes. Unit-wise short notes, an MCQ question bank and a final test paper are provided.
