Haryana Board HBSE Class 11 Chemistry:  Haryana Board is responsible for school-level education in Haryana. Recently, the board has released the marking scheme and model paper for students of classes 9th to 12th. Students preparing for the exam are advised to check the official website for regular updates on exam date sheets. 

Before the exam, it is common to prepare for the exam by practising models and previous year question papers. It’s a key to refining your preparation level and also understanding the question patterns and marking system shared in the sample papers. Especially for science subjects, which require time and practice to solve non-theoretical as well as theoretical questions. Therefore, in this article, we have shared the Haryana Board class 11 Chemistry, model paper with the marking scheme PDFs for your easy access. Check out further to access the links.
