Hey B Uma Maheshwar,

Under B Category Admission colleges consider all india jee mains rank not your Category rank. So, if your jee mains rank is below 1,20,000 then you have maximum probability to get Admission in top 10 colleges. However not all colleges accept B Category Admission. If all the seats are filled through TS eamcet counselling or Management quota, they doesn‘t provide b category seats. To get ECE in CBIT your all india rank must be below 50k. All colleges release b category admission notification through their official webistes or news papers. You need to check every day and once the notification is released you need to submit application. Application cost varies from college to college.
