In ZIO 2025, Apart from determination and hard work, studying smart is also needed. These are some tips and tricks by exam experts which will be beneficial in your preparation for ZIO 2025:

  • Study smart, not more: Studying smart is more important for 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 that 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 come in the ZIO 2025. These 4 questions are divided into 12 parts (3 parts or sub-questions for one main question).

Questions related to ZIO

Have a question related to ZIO ?

Dear aspirant !

Hope you are doing well! The registration for zonal informatics Olympiad (ZIO) will be ended on 24th November 2021 till evening ,so you have enough time,if there is some more related query then ask us anytime.

Hope it helps you !!

Thank you

Hello Aspirant,

Hope you are doing well.

At the ZIO, participants are not expected to know any standard algorithms. It is more of a test of the participant's ability to think and solve problems. Hence generally, problems are of an ad-hoc nature. So doing any particular topics is probably not going to help much. However, if you practice solving programming contest problems, it would be easier for you to think fast and think correct during the ZIO. So I would suggest you to try coming up with algorithmic solutions for Div 2 problems on Topcoder/Codeforces.
However try for these topics:

  1. <Data Structures>
  • Arrays
  • Lists
  • Vectors
  • Queue
  • Stack
  • Graph
  • Linked List2

2. <Algorithms>

  • Basic Knowledge for implementing loops and condition statements
  • Graph Search Algorithms
  • Sorting and Searching Algorithm
  • Divide and Conquer
  • Greedy Algorithm
  • Dynamic Programming

Hope you got the answer to your question. Incase of any queries, feel free to question. Have a great day!
