The Retry exercise feature allows you to easily retry an exercise that you have previously attempted. The following conditions apply to exercises that can be retried using the retry feature.

1. The exercise you want to retry will be restored in your draft data. Therefore, the "Retry exercise" icon will not light up unless you delete your existing draft data in advance.

2. You cannot use the "Retry exercise" function for our custom text correction and diary services.

3. You can only retry exercises that are currently available on IDIY.

Example 1: If you want to retry 1 exercise out of the 10 (9 available 1 unavailable) you have completed in the last 3 months, 1 exercise out of the 9 that are currently active can be restored as a draft, and the 1 exercise that has become unavailable cannot be restored. 

Example 2: If I press the "Retry exercise" button to retry a daily essay exercise that I had tried 3 months ago (the exercise has become unavailable), I will not be able to retry the exercise because there is no available exercise to retry.
