Questions

Which syllabus does this course follow?

The NCVT / DGT CTS (NSQF) Workshop Calculation & Science syllabus for draughtsman trades, Year 1. The centre follows the student's own ITI syllabus where it differs.

Is this course hard for weak maths students?

No, it starts from basics such as fractions and units and builds up with many solved workshop examples.

Can students of other trades join?

Yes, the topics are common to most ITI engineering trades, with examples taken from drafting work.
