Questions

Which syllabus does this course follow?

It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc Computer Science, Semester 4. Where your own university's syllabus differs, the centre follows your university's syllabus and question pattern.

Do I need Linux on my own computer?

Not necessary. The centre's lab has Linux; you may also use WSL or an online terminal for practice.

How are the practicals marked?

The trainer watches each experiment and marks it on a rubric; the viva questions here prepare you for the university practical exam.
