Which stream should I opt in class 11 for game designing?

Hi, As you are interested in game designing, you can pursue game design with class 11th as there are different coaching classes, institutes and various training center in Ahmedabad.

Mathematics and science would be good, since you should know the basics of science. Physics is applied in the games, so it must be very good. You need a strong base in science as it will help you and put you ahead of many others in the field. Good luck.
