Hello Himanshu, 

You have scored 79.50 percentile in JEE Mains and if you calculate the corresponding rank, it would be somewhere around 2,00,000. 

SGSITS is a good college and the cut off goes a little high here. For a SC category student last year cut off rank for core branches was around 1,10,000 for home state candidates. So your current percentile is a little less to get admission in SGSITS. 

I would suggest you to study hard for the April JEE Mains exam and score more than 90 percentile. In this way your rank would be less than 1,00,000 and you will get core branch of your choice in that college. 

All the best. 

Hi dear,

Your percentile is 79.50 that means your rank should be around 225k in general and 13k in your category.you can check here

If you belong from home state then you have a chance to get SGSITS.

Hope it helps
