Questions

Which syllabus is followed?

The current AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) B.Tech syllabus of Engineering Chemistry Lab (Semester 2, all branches (Semester 1 for some groups)). If your university or college follows a different syllabus, the centre teaches from your own university syllabus.

How is the lab assessed?

By the experiment / job performed, readings or output, the record file and a viva voce, as in the AKTU internal and external lab examination.

Do I need a record file?

Yes. The centre helps you write each experiment with aim, apparatus, procedure, observations, result and precautions.
