How were the Lectures for this course?

The overall content covered in the course is easily understandable and the content of the lectures can also be easily grasped. The professor does indulge in some digression and gives some fascinating facts and other general knowledge which is quite helpful to us in the long run (it isn’t quite helpful for the course though). He explains the fundamental concepts very well and goes through each topic at least twice. Also the analysis of the data done in the end is something which was not given in slides and is explained nicely in the lectures. There is 5% weightage for attendance which is taken through the Safe App. I highly recommend going to the lectures on time as the professor tells you to mark the attendance as soon as the class starts and any other time stamps found are marked absent.

How were the Exams for this course?

The quizzes are conducted during a fixed day every week on the Safe App. The quizzes are very easy and generally based on the topics covered in the last week. The questions are mostly multiple choice or numerical. One thorough revision of the slides can easily give a perfect score in each quiz. The mid-sem and end-sem exams are written and have numericals and proofs and many thought provoking questions, including questions of interpretation of the data analysed. They are of moderate difficulty and a deep understanding in the course, especially the various kinds of distributions and linear regression will result in a good score in both exams.

How are the Assignments & Projects for this course?

No Assignments or Projects given. Tutorials were conducted within the lecture hours but did not contribute to any separate weightage towards the grading.

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

The course isn’t difficult and one can easily score a decent grade with a good go-through of slides and by solving tutorial problems and previous years’ papers. Problems in the reference book can be solved for better practice.
