If you are experiencing technical issues, your school or district may have firewalls up that are blocking the MasteryPrep Platform from functioning properly.
Firewall issues can manifest in the following ways:
- Grey or white screen
- Not saving student progress
- Submitting answers prematurely
- Screen flashing
- "Glitches"
- Not able to play videos
Please see our article on how to whitelist the MasteryPrep Platform to solve your firewall issues.
After fully implementing the whitelisting instructions, please check that you and your students are using the most up-to-date version of Google Chrome as a browser. This works best with our platform. If this issue does not resolve once our domains are approved, please let us know so we can further investigate.
