    How to prepare for the IISER Aptitude Test?

    Understand the syllabus

    The first step is to understand the syllabus. Your entire preparation should be based on the syllabus.

By analysing the syllabus, you will become aware of how much time you should spend on each section. The specification for IAT covers the syllabus of NCERT for classes XI and XII in physics, chemistry, maths and biology. Candidates can download the complete syllabus from the official website iiseradmission. in.

    Time Management is Important

    The next step is time management. After the clarity about what is required to be prepared for the examination, the candidate should prepare a timetable that helps them cover all the topics well in time and also allows time for mock tests and revision. The timetable can be set by dividing the number of days left till the exam, the topics to be covered, the difficulty level of the topics and the time required for revision.

    Select the Right Book

    Students often search for the best books for IISER. The knowledge of the best books gives students an edge as they know exactly how to approach the various topics, and they do not waste time looking for resources or materials to prepare. It is important to carefully select one or two reference books and revise multiple times. Students must begin their preparation for IISER 2027 from the NCERT syllabus of classes 11th and 12th. In such a case, preparing from the books listed below gives students sufficient practice with tricky questions and a deeper understanding of topics.

    Practice Sample Papers and Mock Tests

    After preparing the topics with the help of reference books and various other resources, it is required to be familiar with the exam pattern for the IAT. Students should practise last year's question papers and take IISER 2027 mock tests. Also, candidates can improve their time management skills while attempting mock tests. IISER provides sample papers and a mock test as well on its official website. Students can purchase practice materials from the market easily.

    Revision Is The Key

    Revision is another key step in the preparation journey. There is no point in simply learning topics without retaining them and being able to reproduce them in the examination. Instead of searching for new materials and getting confused, it is advised to revise existing study material and stick to the books you already have. Revision helps in revising concepts and ensures that important topics are not forgotten while focusing on new ones.

    Focus On Your Health

    An important aspect of preparation is focusing on your health. As the exam approaches, so does the pressure. No matter how well you prepare, it all goes to waste if you are unable to even attempt the exam. Candidates should therefore pay equal attention to their health so they can stay fit throughout the preparation period and appear for the exam confidently.
