Topics that have been included in the Chemistry syllabus for the current academic year have been mentioned below. Syllabus for the class 11th Chemistry subject has been reduced to 70% as there is less time left to complete the curriculum. Make sure to cover these topics while preparing for the school exams. Candidates can check both included and exclude portion of the UP Board Class 11 Chemistry Syllabus 2022-2023 in this article. The UP board has released the syllabus for the class 11th Chemistry subject after deducting a part of the syllabus. ![]() ![]() Knowing the syllabus of a subject is very important for the preparation of the exam. ![]()
