Questions

Which syllabus does this follow?

The course follows the AKTU (Dr. A.P.J. Abdul Kalam Technical University, Lucknow) first-year Engineering Physics syllabus of the current scheme. Where your own university syllabus differs, the centre follows your university syllabus.

Are derivations covered?

Yes. Important derivations such as Schrodinger equation, particle in a box, Maxwell's equations, Newton's rings, grating and numerical aperture are written step by step.

Do you solve previous-year AKTU papers?

Yes. Previous-year questions and numericals are solved unit-wise before the semester exam.

Is the lab part included?

This course covers the theory paper. Viva questions for the physics lab can be discussed on request.
