Hello GameSan Tech,

First thing first, don't take any Technical Elective, yes I can see you have mentioned that you want to take one, still.

I had my interest in AI and when I saw robotics in the list. I knew that was what I wanted to take, (Physiology was my second option, I still wish I had put that as my first option).To sum up the experience of this OE, all I can say is that, "I liked robotics, I still like AI because we were never taught anything about AI, apparently we were taught robotics and I don't like robotics anymore". Here I mean that it is always better if you pursue your interest without taking a similar OE in the fourth sem. Most of the technical open electives did a good job of sucking out interest as I know from my friends. So take something that is interesting and completely new, you will have a Program Elective in the coming semesters.  I would recommend you to take Linear Algebra then , it is really helpful in Game Development and Machine Learning. But for the Fourth Sem OE go for some Non-Technical Elective. Here are the two I found most interesting.

Advertisement Theory : This is Fun you get to make ads in class and its really fun answering the exam.The cut-off is low too.

Inter-cultural communication: Again Something very interesting and the topics that I have heard that they discussed are interesting.

Now If You still want to take up something that is little towards technical part.

German: Take this and everyone will know that you are the 9 pointer. The cut-off is high for this but you get to learn a new language and that is always great.

Psychology: I don't know what they were taught in the elective, but I have always found it amazing to make predictions by reading someones body language. More over they did not have sessionals.

Total Quality Management : This is where you never attend classes, yes most of the time classes remain canceled.(Take this at your own risk :).

Biology: You get crossword and fill in the blanks to solve.

Before even thinking of deciding on taking an open elective get a good gpa in 3rd sem so that you can get any elective you want. Take an easy and fun elective. You will have Program Electives later too. Explore something different and something new.

.

Hope this helps...

Thank you and all the best...
