The exact dates for Class 10 pre-board exams in Bihar for the 2027 academic year are not yet publicly announced. However, based on the information available, it's likely that the Bihar Board will follow a similar pattern as in previous years, which would mean the pre-board exams would likely be held in January or February of 2027, as these are the months in which many private schools and the CBSE often conduct their pre-board exams.

It's important to note that the Bihar Board often releases the detailed examination schedule closer to the actual exam dates, so it's best to check the official Bihar Board website or authorized educational channels for the most accurate information about the pre-board exam dates for 2027.
