Computer Science

Hi Manojna,
Getting computer Science engineering with this score will be difficult for you. Although, I will suggest you to give a try and participate in counselling. If seats are vacant in final round, then only you will get admission. Otherwise, very low chance is there. Best of luck.

Kindly predict your college in this college predictor. JEE Main rank predictor is an online tool which predicts the candidates rank range and probable colleges based on the difficulty level of the examination, average marks scored in JEE Main and seats available in IITs, NITs, GFTIs, and other SFTIs.
The rank predicted might not be accurate but it certainly does give an idea to the aspirant.

Let me be frank, you percentage is very low and you will find it difficult to take admission in Galgotia for CS. But, for once talk to their admission cell.
