Questions
Which syllabus does the Optical Communication Lab 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.
