JEE Main Scores

You must have scored more than 125 marks to CSE branch in that for all other branches if you have scored more than 85 marks it is more than sufficient.

Yes, As your category is SC, so, it may be some hope to get admission in lower order NITs.

Hello Shruti, Let me tell you something. Our degree is only a step in the ladder of our career. It many a times has no relationship with what we achieve in life. A mechanical engineer today is COO of ICICI Bank and an Aeronautical engineer is CEO of Infosys. Hence my strong advise is to pursue that subject that course which fascinates you without thinking too much of what will happen four years from today. Frankly speaking nobody can predict future.

Since you are from general category. You will not get good colleges. But there will be some colleges who will be willing to take you. But you have to choose wisely.

Sorry to say that you can not get CS in. This college. These are very high facilitated and reputed college of Madhya Pradesh.

With these marks, you can not get NIT. https://www.shiksha.com/b-tech/resources/jee-mains-college-predictor

It changes every year and varies category-wise. So, the cutoff marks in JEE Mains are not constant.

I can't tell the score that you have to get in Mains as it varies every year. But you have to get a rank at least about 10k in JEE Mains to get into aerospace engineering. Then, you will be in the super-safe zone. Up to 15k, you can have a moderate chance.
