According to the official website http://chbsbhu.in/Procedure.aspx admission in the school for Classes 6th, 9th and 11th are conducted through SET which is the School Entrance Test. This SET is conducted by BHU every year around May. But since we have been under lockdown since March, admissions have been postponed. And as the current lock down is also for educational institutions, we might have to wait atleast until 4th week of June for any official information. Please watch out for any such information on the official website.
