Questions

Which syllabus does this Computer Networks course follow?

It follows the AKTU (Lucknow) MCA syllabus for Semester 3. If your own university's syllabus differs, the centre follows your university's syllabus and unit order.

Is subnetting covered in detail?

Yes. IP addressing, subnetting and CIDR are practised with many worked examples, as they are asked in exams and interviews.

How are students tested at the centre?

Unit-wise MCQ tests, numerical / problem practice, previous AKTU question papers and a final mock paper before the semester exam.
