Sri Guru Tegh Bahadur Khalsa College, New Delhi, will be the best option among the Gargi, ARSD, and Khalsa College if the distance is not the parameter.

SGTB Khalsa College is the oldest college with the best infrastructure and phenomenal teaching faculty. Every facility is available in this college.

For Maths Hons, I suggest you prefer SGTB Khalsa over other colleges; else, ARSD is not a bad option.
