This is a common issue.

The reason is because this website is a different website than https://HowToTunePianos.com where all the lessons are.

We use this website so you can track your progress.

To solve the problem click the LOGIN menu item, look for the link below the login that says “Register” and register for an account with any email and password you choose.

Then you can access the quizzes in one of two ways:

1. Click on Quizzes in the menu and navigate to the lesson quiz you were looking for, or,
2. Click the “Take the Quiz” button again on the HowToTunePianos.com website.

IMPORTANT NOTE! If you know you are logged in but you still can’t access the quiz, try reloading the page.
