How were the Lectures for this course?

The course has really great content and the professor explains it very well. I would personally recommend attending the lectures and taking notes during the lectures as the professor does discuss a few things during the lectures which are not present in the slide and contribute to a significant amount of weightage in the mid-sem and end-sem. His lectures are also available on cdeep for future references.

How were the Exams for this course?

Quizzes are easy and one can score in them with a quick revision on various terms, processes, proofs, formulae etc. They have both theoretical and numerical questions. Theory mostly includes definitions, explanation of processes and simple reason questions and the numericals are also almost direct application of formula. Mid-sem and End-sem are very tough and are graded on the basis of a strict pattern. The numericals are based on tutorials but do come with a twist which needs to be thought out. The theory as mentioned earlier contains questions whose reasons have been discussed during the lectures. Theoretical questions are not direct definitions, they make you think a lot. All of these are, however, doable with an in-depth understanding of all the concepts and lecture notes. The course does tend to have more of a theoretical aspect in many questions which are not numericals directly.

How are the Assignments & Projects for this course?

No Assignments or Projects were given in the course. A few tutorials were conducted during lecture hours itself which did not contribute to the final grade.

Any tips for the junta to perform well in the course?

I highly recommend attending lectures (how many ever are conducted) and taking class notes during lectures as many questions are directly asked from what he teaches in the class and is not present in the slides. Solving the tutorial problems and past years’ papers and going through the slides is enough apart from that. For having a better insight in the concepts one can read the reference books. I would also suggest to read the questions carefully during exams and see what it is demanding. Although it might be tempting to answer some things numerically or through formulae, but sometimes the professor wants a theoretical explanation for the same. So you need to be good at providing good theoretical explanations as well as solving.
