Hi,
Once you've completed all six tests you should have the option to reset them yourself. Once you do so, you will still see the original 6, however you will have the opportunity to continue to take more tests, and they will appear as 1A, 2A, etc. I just looked in your profile and saw that you are currently on test 1A, which means you were successfully able reset your tests.
If you have any questions about this, please feel free to email us at
