i let here my recent personal project. a Quiz with general questions.
Its a MERN app and is deployed in Heroku.

Feel free to play it and record your scores.
Feel also free to review it and give feedback for improvements and corrections
Double check grammar and use it consistently throughout (use US & USA or use U.S. & U.S.A.) rather than a mixture. Over all great though.
I really enjoyed your quiz! It looks really, really nice, and I really like how you implemented a leaderboard for it!
One thing that I would add is to show the user what the correct answer was when they get one incorrect.
Other than that, it looks really good!
