Hi,

All of the colleges that you have mentioned are among the decent colleges of DU. They are all mostly at the same level. Indraprastha College for Women is the best among these for Maths hons. 

After it, you may prefer Shaheed Bhagat Singh and Ramunajan colleges who are known for their good infrastructure and studies. Ultimately, you would be getting a reputed degree from Delhi University, no matter which college you choose. So, you may consider other factors too while choosing your college like location, extracurricular societies etc. 

All the best!
