    Apart from determination and hard work, studying smart is also needed. These are some tips and tricks which may be beneficial in your preparation for ZIO 2026:

    • Study smart, not more: Studying smart is more important than studying more. Get a notebook and write down the complete syllabus. Sort out the topics into categories like 'Prepared, not Prepared, have to revise, etc.' This will give you an overview of the amount of time you need to give to a particular topic and help you study smart.
    • Make a Study Plan: Making a study plan makes you more consistent towards your studies and allows you to give a set amount of time for everything you do. This is important as most of our time is spent doing idle things. Making a study plan diminishes the chance of wasting your precious time.
    • Learn the syllabus: By heart. Being aware of the complete syllabus and the important topics is the first step in realizing the areas of strongholds and the chinks in the armour of your preparation. Read the syllabus completely and analyse it accordingly.
    • Practice from sample papers and mock tests: Sample papers and mock tests are very important as they help you analyse yourself. After completing a topic, make it strong by giving a mock test or solving a sample paper.
    • Understand the standard of questions and the Exam Pattern: Understanding the standard of questions enables you to prepare for the topics accordingly. Exam pattern and previous year question papers show us that a total of 4 questions will come in the ZIO 2026. These 4 questions are divided into 12 parts (3 parts or sub-questions for one main question).
