Questions

Which syllabus is followed?

The NCVT / DGT CTS Workshop Calculation & Science Year 1 syllabus for mechanical group trades. Where your ITI (SCVT) syllabus differs, the centre follows your own syllabus.

Are workshop examples used?

Yes. Problems use plates, bars, gears, lathe speeds and other examples from the Fitter, Welder and MMV trades.

Is this useful for the CBT exam?

Yes. Chapter-wise MCQs and full mock tests in CBT pattern are given.
