Hi Rina,

You cannot edit your list of desired courses now. It was possible only till the last date of DU online registration, which was 22nd June, 2019. After the registration dates are over, one can only edit their marks and nothing else from the form. 

Hence it is advisable that you fill each and every course you even have an iota of chance doing, since there are no extra costs attached to choosing more courses. However, I would suggest that you choose from the courses you've applied for. Choose the one you're interested in. Delhi University is worth it! 

Otherwise you'll have to look for some other college/university. 

All the best!
