Dear Aspirant,
The general rank cutoff for NIT Delhi is around 6000 AIR. There are around 14 lakh students sit in the exam of jee mains, and getting a rank this good is definitely hard. However, it is not an impossible task and I suggest if you prepare with honesty and dedication then you can get into the NIT-DELHI.
If you are a week student, then I suggest you should take a drop and take coaching from some good institute like ALLEN, KOTA. Then give the exam with your preparation, maybe you get CSE in IIT-DELHI.
Hope this helps.
