AHSEC Class 11 Physics Syllabus 2023-24: Assam Board HS Exam Pattern and Marking Scheme

Assam Board HS Physics Syllabus 2024: Physics is one of the important subjects science students study in every educational institution. The concepts of physics are important and difficult to understand. It has been said that the Class 11 Physics syllabus is tougher than the Class 12 Physics syllabus because students tend to face complicated theorems and formulas for the very first time in Class 11. Thus, if something has been changed or removed from the physics syllabus, it becomes highly important for students to know. The best way to know the revisions in the syllabus is to check the newly released syllabus and compare it with the previous syllabus.

To help AHSEC HS 1st year students of Class 11 science, we have provided the newly released Assam Board Class 11 Physics syllabus. This Assam HS Physics syllabus 2023–24 will be followed for the 2024 HS examination for Class 11. Students are advised to go through this article once to check the AHSEC HS Physics syllabus and paper pattern. The PDF is attached for free download.
