There are two possible reasons for this:
- Quiz Score: You need to get a perfect score (100%) on the previous module's quiz before unlocking the next one.
- System Delay: Sometimes, there might be a short delay after completing a quiz before the next module becomes available.
Here's what to try:
- Check your quiz score: Make sure you received 100% on the most recent quiz.
- Wait a few minutes: Occasionally, there's a brief delay in unlocking the next module. Try waiting a few minutes and then check again.
- Refresh your browser: A simple refresh can often resolve minor glitches.
