Bangalore: Are empty classrooms going to "greet" engineering and dental colleges in the state this year? With only a week remaining for the single window counseling for B.E and B.Tech seats, the state is worried about more than 22,000 vacant seats across 250 colleges. According to the Karnataka Examination Authority (KEA), unbagged seats rolled up to an enormous 13,000 after the Common Entrance Test (CET).Around 9,328 seats were vacant after final round of counseling of ComedK. In short, vacant seats are likely to be numbered around 22,000 this year. Astonishingly, there are around 30 colleges without a single taker through ComedK. In universities like Alva's Institute of Engineering and Technology and Coorg Institute of Technology, their 126 and 108 seats respectively are not even considered after counseling.
