Questions

Which syllabus does this course follow?

It follows the UP State Universities NEP 2020 common minimum syllabus for B.Sc. Where your own university's syllabus differs, the centre teaches your university's units and papers.

Are numericals practised?

Yes. Every unit has solved examples and practice numericals at university exam level.

Is the derivation of Maxwell's equations required?

Yes, standard derivations (wave equation, Poynting theorem) are taught step by step as asked in university papers.
