Hey Karan ,
The reason to choose Delhi is as it provides a good opportunity for management as well
The arena for management as a post graduation degree is cluttered with millions of aspirants , and there are various exams conducted to grant admission to students but the competition being so steep it is inevitable for students to take coaching for proper guidance .

Some of the institutes are
1. IMS Learning center

2. Career launcher

3. Triumphant institute of management pvt ltd

4. Catking

Hope this helps , all the best !
