Questions

Which syllabus does the Materials Engineering course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Materials Engineering. 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 previous-year question practice, MCQ tests and doubt sessions before the semester exam.

Is the iron-carbon diagram explained in detail?

Yes. The full Fe-Fe3C diagram, its reactions and lever-rule numericals are taught because they are asked every year.
