Greetings aspirant!

Generic elective subject is basically those subjects that you can study along with your main/core subject.  Now different colleges in delhi university provides different generic elective. And you can get zoology being a commerce student only if below mentioned criterias are there.

So you getting G.E in your college will depend on if the college has the particular course i.e zoology , if the college provide that particular course as a GE subject, and the number of seats available.

You can download brochure of the college you are interested in from careers360 and can look up for generic elective subjects they provide in the brochure.

Hope you find it helpful. Thankyou!
