You can test your React skills with W3Schools' Quiz.
The test contains 25 questions and there is no time limit. The test is not official, it's just a nice way to see how much you know, or don't know, about React.
You will get 1 point for each correct answer. At the end of the Quiz, your total score will be displayed. Maximum score is 25 points. If you don't know React, we suggest that you read our React Tutorial from scratch.
