Professor’s Teaching Style: Flipped classroom system was followed. Ma’am uploads the videos on BodheeTree and you have to watch before the class. Ma’am will discuss the major point and then some hands-on exercises will be there. Sometimes it can happen that you won’t be able to watch videos before the class. I personally found it boring to sit in the hostel room and watch these videos. But, yeah ma’am teaching really nicely. She gives every effort for providing better learning experience as well as the implementation of the course. Labs are directly from what she discusses in the class exercises. Exams are based on slides, but with a lot of twists. Grading is not much good, because I found it genuine because after doing so much effort, ma’am can expect more from you.
Should you do this course?: If you really want to know about what is inside title of the course, I definitively recommend this course with a condition that you would need to do effort. Course will provide a lot of opportunities for practical aspects and you can learn a lot. Stating again, time commitment is a pre-requisite.
