A mock exam is a rehearsal of the real exam under real conditions: the same kind of questions, the same time limit, no notes. Its value is in what you do afterwards, when you read the result and go back to what you missed. A Diaposi mock exam ends on a grade out of 20 and on what to revise next, weakest chapter first.
What is a mock exam?
A mock exam is a practice exam sat under the conditions of the real one: the same kind of questions, the same time limit, no notes and no pausing. It is a rehearsal, not a lesson. It does not teach you the material. It shows you what you can do with it today, which is the information you need to plan the days that are left.
Why does rehearsal work?
An exam tests more than knowledge. It tests whether you can find what you know under pressure, manage the time, and keep going after a question you cannot answer. None of that can be practised by reading. A mock exam also replaces a vague worry with a list: these chapters are fine, those are not.
How do you use the result?
- Read the mark last. Start with the questions you missed.
- Sort the mistakes. Did you not know it, misread the question, or run out of time? Each has a different fix.
- Group them by chapter. The weakest chapter is your next study session.
- Sit another one. New questions, the same chapters, a week later.
Take the first one earlier than feels comfortable, when there is still time to act on it. To build one, see how to create a mock exam from your lecture notes. To run one for a group, see how to run a mock exam for your class.
How a Diaposi mock exam helps

A Diaposi mock exam is built from your own course files and sat like the real thing: the questions stay hidden until you press Start, and the clock keeps running if you leave. You get a grade out of 20 with every question open to review, and what to revise next comes weakest chapter first, with the pages to reread in your own course.

Frequently asked questions
When should I take my first mock exam?
- Two to three weeks before the exam, once you have covered most of the course. That is early enough for a bad result to be useful.
Is a low mock exam mark a bad sign?
- It is information. A low mark three weeks out, sorted by chapter, is a study plan. The same mark the night before is only a number.
Is Diaposi free?
- Yes. Diaposi is free, and there is no paid plan today.
