tell me 30-40 days courses in computer game development so i can do in my vacation presently i am doing b.tech in c.s means semester vacation

you can contact any multimedia institute near u and can choose a course as per your convenience.

no course can be done in 30-40 days especially computer game development maybe you could go for smaller courses say ..photoshop,web designing etc...which can be covered up in a month visit:-www.tekhnix.com
