What are the chances of getting admission in Jai Hind College, SK Somaiya College, and HR College Mumbai after a drop year and with 70 in the SC category?

Hope you're doing well.

Don't stress about taking a gap year; it won't block your admission chances. The course you choose is what really matters. Some courses like BSc in Physics (Hons) and BA PS (Hons) might be tougher to get into, but I'm not entirely certain. It's a good idea to look at the previous year's cutoffs to get a better idea. Being a girl and in the SC category definitely works in your favor. In my opinion, there's more than a 90% chance you'll get into these colleges.

Good luck!

Taking a drop year won't impact your admission chances at all. With your category, you stand a strong chance of getting into the colleges you mentioned. Just focus on picking a course you enjoy and select the college that fits it best.
