Does quizzing yourself actually work?
Yes - And it is one of the most well-supported findings in educational psychology. The effect is called the testing effect or retrieval practice effect. In study after study, students who tested themselves on material remembered significantly more than students who spent the same time re-reading their notes.
A landmark 2011 study in Science (Karpicke & Blunt) found that students who practiced retrieval retained 50% more information a week later compared to students who used concept mapping or repeated study. The act of pulling information out of your memory is itself what strengthens the memory trace.
Why is self-testing better than re-reading?
Re-reading creates a feeling of familiarity - The words look familiar so you assume you know the material. But familiarity is not the same as being able to recall it under pressure. Quizzing yourself exposes the gap between recognising information and actually knowing it.
When you fail to answer a quiz question, three things happen:
- You discover exactly which topics need more work
- The correct answer becomes more memorable because of the failed retrieval attempt
- You build the same neural pathway the exam will need to activate
How can I turn my homework into a quiz?
The easiest method is to use an AI quiz generator. On DoQuizzes, the process takes under a minute:
- Go to the AI Quiz Generator
- Paste your homework text, class notes, or a topic description into the input box
- Choose how many questions you want and pick a quiz format
- The AI generates a full quiz - Questions, answers, and multiple choice options
- Play it immediately or save it to your account to revisit
You can use text from any source - Textbook paragraphs, your own handwritten notes typed up, a Wikipedia article on your topic, or even a past paper question. The AI extracts the key facts and turns them into quiz questions automatically.
How often should you quiz yourself while revising?
Ideally, quiz yourself at the end of every study session and then again 24 hours later. This is the simplest form of spaced repetition. The first quiz tells you what you know now; the second quiz, taken the next day, forces your memory to reconstruct the information again - Which is what locks it in.
| Timing | Purpose |
|---|---|
| End of session | Check immediate comprehension, spot gaps |
| Next day | First spaced retrieval - Most important |
| 3 days later | Second spaced retrieval - Consolidates memory |
| 1 week later | Final check before moving on |
What is the testing effect?
The testing effect is the scientifically documented finding that retrieving information from memory strengthens memory more than restudying the same material. It was first systematically studied in the early 20th century and has been replicated hundreds of times since.
The reason it works is that retrieval is an active process. When you try to answer a question, your brain searches for the relevant neural pathways. Whether you succeed or fail, the very act of searching reinforces those pathways. Each time you successfully retrieve a fact, the memory trace becomes stronger and more resistant to forgetting.

How can quizzes improve memory retention?
Every time you answer a question correctly, the memory is strengthened. Every time you answer incorrectly and then see the right answer, the contrast makes the correction stick. Over multiple spaced sessions, the material becomes deeply encoded rather than held in working memory.
The key is to make it slightly difficult - Not so hard you get everything wrong, but not so easy that it feels like a formality. The "desirable difficulty" principle shows that material studied under moderate challenge is retained far better than material that came easily.
