सवाल
Is a design data book used?
Yes. Students learn to use the PSG / standard design data book and IS tables as allowed in the exam.
Are drawing sheets part of the course?
Yes. Designed joints, couplings and shafts are also drawn to scale as per the syllabus.
Is this course based on the BTEUP syllabus?
Yes. The units follow the BTEUP (Board of Technical Education, Uttar Pradesh) diploma syllabus. If your polytechnic follows a different board or a revised scheme, the centre teaches your own syllabus.
