hiii smriti

to get Computer Science and Engineering in the first round of the councelling you have to get rank in JEE around 4.5 k rank as such you are general right you have tough competation

Hi Smriti, the most important criteria is firstly to get 80% aggregate in the board exams. 

If you're from delhi then your has to be around 4k and if you're from outside Delhi then your rank must be around 1-2k.

I'm not very sure about the marks but it should definitely be more than 250. 

Hope the answer helps you!
