Yeah.. everybody knows and acknowledges University of Delhi as some of the most prestigious and reputed academic centres in India. Though it is up to you how you utilize its potential. If you expect too much from professors, then you might be on wrong track. In the end, be it academic excellence or your passion , you have to work it out yourself. For sure teachers are guiding and you get a lot of exposure and platform to showcase your potentials but keep in mind you have to grind yourself to get over others. Best of luck.
