I tried ChatGPT's new interactive quizzes on 5 subjects I thought I knew well — it quickly found the gaps in my knowledge

ChatGPT has a new interactive quiz feature, designed to make testing yourself a more active part of using the chatbot.

Instead of asking ChatGPT to explain something and then nodding along because everything looks familiar, you can have it put you on the spot.

It's part of OpenAI's steadily expanding learning toolkit, building on Study Mode and other features.

I picked five subjects where I felt reasonably confident, but it turned out to be a very efficient way to locate the holes in my knowledge.

How to use the quiz feature The quiz feature is available to anyone.

You just need to prompt ChatGPT by asking for it.

I decided to start with a quiz about AI itself, specifically its history.

But I didn't want to just have very basic questions, so I made sure to ask for the quiz to be at a certain level.

And while you can ask for a short essay answer format, I opted for the classic multiple-choice style, and for help with where I went wrong.

My exact prompt asked ChatGPT to: “Quiz me on the history of AI at a college level with 10 multiple-choice questions.

Don’t show me the answer until I respond.

Explain anything I get wrong and give me my score at the end.” The one-question-at-a-time format made a bigger difference than I expected.

A conventional online quiz often gives you a page full of questions, followed by a score and perhaps a few explanations once you are finished.

Here, ChatGPT reacted after every answer, briefly explained the result, and moved on.
