Hello there, hope you are doing!

As you live in South Delhi, the travelling to both colleges would be in a way similar to you. Between Kirori Mal College and Sri Guru Tegh Bahadur Khalsa College, both are great options for Bcom Honours, while KMC has slightly better placement history as compared to Sri Guru Tegh Bahadur Khalsa College. You can choose any of the two options confidently.

Hope you found this answer helpful.

Good luck for your future!
