Hello Jayashri.

Hope you are doing good in this current COVID situation.

According to your income (i.e. 550000) you are eligible for Supernumerary Quota in all the Engineering colleges in Karnataka automatically. Also not all the eligible students will get this SNQ quota.

Only few students in every colleges will get this SNQ quota. And this quota is given to students based on the income and ranking in KCET .

As you are eligible, you have the chance of getting Computer Science Engineering seat in Supernumerary Quota in St. Joseph Engineering College.  Hope for the best.
