Hey ishika, 

For both economics honours and bcom hons At 92.75% it is very difficult to get into any top south campus College flike gargi or venkteswara but you can make it to off campus Colleges like deshbandhu, zakir Hussain. This is assuming you belong to general category

If you have reservation then you can get into a better college. 

Hey Ishika,

Yes you can get admission in south campus colleges like- Motilal Nehru College,  Aryabhatta College, Ram Lal Anand College, You can also try for Vekateshwara college, if this time there cut off percentage gets to 92% in any of the cut off list. Also, calculate your best four according to the course you are seeking admission to. I hope you get what you want :)

All the best!
