Haryana Board HBSE Class 11th chemistry Syllabus 2025, Download FREE PDF

Board of School Education Haryana (BSEH), also popularly called HBSE, is the official education board of Haryana responsible for conducting annual board exams and providing students with relevant study materials required for the successful conduct of the academic session. Recently, BSEH released the official syllabus for classes 9, 10, 11, and 12 on their official website. Searching for an authentic syllabus often becomes a troublesome task, hence, we bring you a subject-wise syllabus articles series for all classes of the Haryana Board. Here, you can find the HBSE Class 11 Chemistry Syllabus 2025-26 along with a PDF download link of the same. 

Along with the Haryana Board Class 11 Chemistry Syllabus 2025, this article will also provide you with question paper design, course structure, internal assessment details, evaluation scheme, prescribed books, and monthly teaching plan. The curriculum designed and presented by the board is both student and teacher-centric. On one hand, where students can get a brief about the course content to study along with the marking scheme, on the other teachers can get a fair idea of the vastness of the syllabus, the time they have to ensure complete coverage of the syllabus, teaching plan, and more.
