What is the free Information I Algorithm Quiz?

The Information I Algorithm Quiz is a free 4-choice web app for practicing algorithm thinking, pseudocode reading, flowcharts, tracing, and basic programming logic.

Students can review variables and assignment, conditionals, loops, arrays, linear search, binary search, sorting, data processing, and simple complexity questions through short original quizzes.

Practice algorithms step by step

The questions are designed to help students read a short process, follow variable changes, check array positions, and choose the correct output, final value, comparison count, or purpose of an algorithm.

Each question is self-contained, so it can be used for quick daily practice, class-test review, or basic preparation for Information I exam-style thinking.

Dynamic hints with original diagrams

Hints change according to the current question. They may show an original trace table, array diagram, search path, flowchart branch, loop value change, sorting before-and-after view, or simple work-growth chart.

These hints are meant to help students understand how to think through the process, not just memorize the answer.

Useful for students, teachers, and families

Students can use the quiz for short review before class, quick checks after learning a topic, or repeated practice of questions they missed.

Teachers and families can also use it to see which parts of algorithm thinking are difficult: tracing values, reading pseudocode, counting loop executions, or understanding search and sorting procedures.

How to use this quiz effectively

Start with the basics mix, then choose a topic such as arrays, loops, search, or sorting. When a mistake occurs, open the hint and trace the values again with the diagram.
