IB ACIO Mock Test 2026
Practise for IB ACIO with timed online mock tests, section-wise analysis and progress tracking on Testkart.
IB ACIO mock tests are the fastest way to learn how the Tier I paper feels under time pressure. The online test has 100 questions in 60 minutes, five equal sections and a penalty of one-fourth of a mark for each wrong answer. That mix of speed, accuracy and risk is hard to judge from reading alone, so regular timed practice matters as much as the syllabus.
The pattern below is from the latest completed cycle, ACIO-II/Exe 2025, and is indicative for the next one.
Types of IB ACIO Mock Tests
Test type | What it covers | When to take it |
|---|---|---|
Topic-wise test | One chapter, such as percentages or blood relations | Right after you finish a topic |
Sectional test | One full section of 20 questions | Once your basics are steady |
Full-length Tier I mock | All five sections in 60 minutes | Weekly in the middle phase, more often at the end |
Current affairs test | Monthly and weekly events | At the end of every month |
Descriptive practice | Essay, comprehension and long answers for Tier II | Weekly, checked by a mentor or peer |
The Pattern to Practise In
In the 2025 cycle, Tier I had 20 questions each in Current Affairs, General Studies, Numerical Aptitude, Reasoning and English, with a single 60-minute limit. Set your mock to the same limit and use the same marking. Tier II, a 50-mark descriptive paper, cannot be fully practised through multiple-choice tests, so pair your mocks with handwritten answers.
How to Use Mock Tests
Weeks 1 to 4: Take one topic test after each chapter to check your basics.
Weeks 5 to 8: Add two or three sectional tests a week, focusing on your weakest section.
Weeks 9 to 12: Move to one full-length mock a week and review it the same day.
Final month: Take a full-length mock every two to three days and revise your error log between them.
How to Analyse a Mock
A mock helps only if you study the result. Spend at least as long on the review as on the test.
Wrong answers: Sort them into concept gaps, careless errors and guesses that failed.
Slow questions: Note the ones that took more than 90 seconds and find a faster method.
Skipped but solvable: These are lost marks. Practise attempting them in the second pass.
Error log: Write every mistake and its fix in one place, and re-read it every weekend.
Benchmarks to Track
Accuracy: Aim to keep it high enough that the 0.25 penalty does not eat your gains.
Attempts: Note how many questions you attempt per section, and avoid adding blind guesses.
Sectional score: Keep every section above your target, not only your best one.
Net score: Compare it with the Tier I minimum for your category, and keep a clear margin over it. See the IB ACIO cut off page for the qualifying marks.
Common Mistakes
Taking mocks without review: Many attempts, little improvement.
Ignoring current affairs tests: This section is quick marks and should not be left for the last week.
Skipping Tier II: A strong Tier I score can be wasted without writing practice.
Guessing heavily: Random guesses cost marks under negative marking.
