How to Score 100 in Chemistry Class 12 Exam? - Tips to Tricks

Listed are some of the proven ways on how to score 100 in chemistry class 12 exam. These have been compiled as per the advice of previous year toppers and subject experts for chemistry class 12.

Understanding Updated Syllabus: The first step in the class 12 chemistry preparation strategy must be to look at the updated exam pattern, which can be found on the official website of the educational board one is associated with. It is important to use the updated study material to avoid wasting time on irrelevant topics. While most educational boards have a syllabus similar to the CBSE class 12 chemistry syllabus, it is important to refer to the syllabus prescribed by the relevant educational authorities.
Studying the Exam Pattern: Students must also look at the exam pattern, helping them understand the marking scheme, important topics, and overall flow of the question pattern. While most boards follow a pattern similar to the CBSE Class 12 exam pattern, it is important to visit the official website and check the one specific to one's educational board.
Creating an Effective Time Table: It is said that the best way to improve something is to measure and that is what a properly created exam time table does. Students are advised to thoroughly think through their subjective needs and create a time table that caters to both their weaknesses and strengths.
Revise, Revise, and Revise!: Whatever students are studying regularly, it is important to revise it once or twice in a week for better retention. Not revising the syllabus can lead to forgetting the important concepts at the last moment.
Practice Previous Year Question Papers: Once students have studied their syllabus, they must start solving as many class 12 chemistry previous year question papers as they can. It will help them analyse the important topics and section-wise marking scheme, and increase their confidence levels.
