Questions

Which syllabus does the Computer Aided Design course follow?

It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Computer Aided Design. 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 software training part of this course?

This is a theory elective. Concepts are shown in CAD software, and the CAD and CAM Lab covers hands-on modelling.
