Questions

Which syllabus is followed?

The NCVT / DGT CTS Electrician (NSQF) Year 1 trade theory syllabus. If your ITI (SCVT) syllabus differs, the centre follows your own syllabus.

Are numericals taught?

Yes. Ohm's law, series-parallel circuits, energy bill, capacitor and AC calculations are practised step by step.

Does this prepare for the CBT exam?

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