सवाल

Which syllabus does the Optical Communication course follow?

It follows the current AKTU B.Tech (ECE) scheme, Semester 7. If your university or college uses a different scheme, the centre follows your own university syllabus.

Do you cover numericals and previous year questions?

Yes. Each unit is taught with solved numericals and AKTU previous-year questions.
