Bihar Board exams for Class 10 and Class 12 are usually held every year in February. For example, the Class 10 exams in 2026 are scheduled from 17 February to 25 February, and the Class 12 exams are from 2 February to 13 February according to the official Bihar School Examination Board timetable. The board releases the complete date sheet around late November or early December, allowing students to plan their preparation accordingly. These exams are conducted only in Bihar for students under the Bihar School Examination Board. If you are asking about any madrasa or scholarship exams in another state or country, they are separate and not connected to the Bihar Board schedule.
