Hii Gurumanveer..

First of all congratulations as you have performed quite well your Board examinations and now you can expect a good college in Delhi University with your best of 4 results.

I think there will be a fall in the cut off for BA programme in Miranda house but since you have got a good percentage you will surely get admission in other good colleges as well. So I would suggest you to better go for any other good college but do not settle for it until the other round of cut off are released and if you get your desired college then switch to it.

Usually there is a fall down in cutoff but sometimes it happens that the cutoffs increased due to high demands of that particular subject and program. Thus it will keep you on a safer side. And later when there is fall in the cutoff percentage then you can switch to your desired college.

Hope this helps.

Best of luck for your future.
