Yes, you are eligible for the SNQ (Supernumerary Quota) seat at BIET College, Davanagere because your annual income is Rs 40,000, which is below the required limit of Rs 6 lakh.

The college keeps 5% extra seats in each course for students under SNQ quota. For example, in Computer Science, if there are 360 seats, around 18 of them are for SNQ students. These seats are given only to students with low income and good KCET ranks.

Your KCET rank is 28,560. Whether you get a seat under SNQ depends on how many students with better ranks than you also apply for SNQ. So, you have a fair chance, especially if you apply for branches with slightly lower demand.

Make sure you have your income certificate ready during the KCET counselling. If you choose your options wisely, there is a good chance you can get a seat under SNQ in BIET.
