Hey Abhi Lash,

The B-Category Admission varies from college to college. Few colleges accepts B-Category admissions and few doesn’t accept. The colleges which doesn’t accept b Category Admission calls them as Management Quota Or NRI Quota. There is no specific date for b Category Admission. Because as the admission is based from college to college. The B Category Admission notification is announced through either college official website or the Telugu leading news papers. I recommend you to check the websites and news papers every day to stay updated. If you go through b Category Admission then you cannot avail fee reimbursement. 

All the best!
