Hello,
See, these three colleges you mentioned, all of them are very, very good. They are one of the premier institutions in our country for degree courses. It is difficult to choose among these three. But, however, Kirori mal college has a special place when it comes to physics honours. This college is known for its science faculty and studies in this discipline. So, i would suggest you to go for Kirori Mal college. However, Ramjas and Sri venkateshwara colleges are also very good for bsc physics hons. So, either of them would be good enough for you to grow and bloom in life.
