# How to top up diamonds

Diamonds are used for AI-scoring Speaking practices on FLYER. If you want to receive detailed scoring & feedback by FLYER AI for your Speaking exercises, you'll need to top up diamonds in your account.

* Step 1: Log in to your account at <https://exam.flyer.us/exam> -> Go to your profile by clicking on your avatar

You can also purchase more diamonds directly on the Speaking test screen by clicking on the diamond icon. This makes it easier when you've already decided on a challenge to practice but find out that your diamond number is sufficient.
