You can get seat through b category .

Every year there are b category seats for students through JEE main score.

U can get seat in vasavi but  one cannot guarantee seat in computer science or information technology.

As the competition is tough you have chance for cse or it based on previous year statistics it was 33 k for cse

Hey buddy, you have a chance to get admission into vasavi college if your rank is under 43k

Hello sunnihithreddy,
