Questions
Which syllabus does the Machine Design-II course follow?
It follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus for Machine Design-II. 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.
Are design data books allowed?
Most universities allow a design data book in the exam; we teach selection of values and standard sizes from it.
