Waiting for a good college for admission in DU highly depends upon your marks. 

If you have scored brilliantly and you are getting desired college then there is no point to wait for 2nd or 3rd cutoff. 

But at the same time you can take admission in one college in 1st cutoff and then later on cancle it if you are getting a better college. 

The second option is risk free and most of the candidates go for it. 

Always happy to help you 

Thanks
