I have 6230 rank in keam and a chance to get du for bsc.which is better

Hi, the choice is upto you, if you wish to go for colleges under keam and apply in the counseling and get a good government college, then it's the best. But if in case you don't get a college of your preference then I would suggest you to go for DU since the faculty and exposure in DU, you won't get this anywhere else. 6230 is a good rank and can bring you a government seat. You should go for both the counseling and have all the options and then decide at the end which place you want to go for.
Hope this may help. All the best.
