सवाल

Which syllabus does this course follow?

The NCVT / DGT CTS (NSQF) Fitter Trade Theory syllabus for Year 2. The centre follows the student's own ITI syllabus where it differs.

Is this course only theory?

Yes, this is the trade theory paper. The matching Fitter Trade Practical course covers workshop jobs.

Will numericals be taught?

Yes, cutting speed, taper set-over, gear and belt speed ratios, limits and fits and hydraulic force are practised.

Does it help in apprenticeship tests?

Yes, the topics match the AITT and the theory questions asked in apprenticeship and industry entrance tests.
