Assam HS Syllabus 2021

Assam Higher Secondary Education Council (AHSEC) has reduced the syllabus for class 11th and class 12th by 30%. The decision was made last year considering the COVID-19 pandemic and the subsequent lockdown. However, the board has decided to go with the reduced syllabus for the year 2021. As the students could not attend the classes for months, the board then decided to reduce the syllabus by avoiding the repeated content in the syllabus to an extent.

All affiliated institutions, including government and private schools, follow the same syllabus given by the Assam HS Board. Candidates can refer to the syllabus given here for the preparation of the Board examination. The question paper for the board examination will also be set as per the new updated syllabus.
