सवाल

Which syllabus does this course follow?

The NCVT / DGT CTS (NSQF) Workshop Calculation & Science syllabus for mechanical-group trades, Year 2. The centre follows the student's own ITI syllabus where it differs.

Is a calculator allowed?

A simple scientific calculator is used in class; trainees also learn to use tables and rough checks.

Is the course useful for other exams?

Yes, the same maths and science topics appear in apprenticeship, railway (ALP / technician) and other trade-based tests.
