Why Attempting Past Test Papers are Important for Exam Preparation?
Test papers are mainly class test papers that the subject teacher had prepared in the past for previous students. Thus when students attempt such practice test papers they get to know the framework which the subject teacher is following in making examination papers. Apart from reference books and notes, Test Papers are very effective study materials for exam preparation. When a student tries to attempt previous test papers , it becomes very easy to gauge how well the topics have been understood and what kind of questions are asked in exams related to that chapter.
As they say before facing the main battle one needs to practice on small fights and get expertise and that will make sure the success in the finals. Similarly in order to score high marks in annual exams, it is imperative to attempt previous test papers so that the student identifies and checks whether the understanding of all concepts of the already prepared chapters of any particular subject are complete or not. It highlights the weak areas if any and gives students ample amount of time to revisit the topics and work on those areas and be better prepared before exams.
Periodic Test papers, Weekly tests and Unit Test papers are usually framed on few chapters of the syllabus thus the concentration of questions asked are of good depth thus when a student attempts those papers, it makes sure that no topic or fundamental concept has been skipped by students while studying any chapter.
