Attempting the practice tests play a key role to make perfect exams. They make the students aware of the topics they need to master in. They help to revive what students have learned till the time. Thus, taking the practice tests can actually be more beneficial to learning than spending the same amount of time in studying. This article provides you with the unitwise practice papers for class 12 Chemistry. Each paper is designed by keeping the exam’s perspective in mind and covers all the important questions from the chapters coming under the respective unit.
