The Board of Intermediate Education on Saturday announced Dasara holidays for Intermediate colleges from October 2.
The colleges will reopen on October 10.
The BIE officials warned that severe action would be taken against colleges which conducted classes during the Dasara holidays, violating the Board's instructions.
Many private intermediate colleges in Telangana are highly rigorous in their training of students for competitive exams, and routinely conduct classes on holidays, which is most likely what prompted the BIE to issue its warning.
