सवाल

Which syllabus does the Measurement and Metrology course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Measurement and Metrology. If your own university's syllabus differs, the centre follows your university syllabus.

Will this help in the university examination?

Yes. Teaching is unit-wise as per the AKTU scheme, with numericals, previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Is this linked to the Metrology Lab?

Yes. The theory explained here is practised on real instruments in the Measurement and Metrology Lab of the same semester.
