the lessons in level 11 will not show that I have finished them.
I have finished them several times. This problem has been for several months.
Hi, try to pass the lessons using a different platform. If you've been using the computer but have a tablet or smart phone, try passing them on one of those. This has helped a few people. The other option is to reset the course and test-out if you're sure you've learned the material. This last option could reset your streak, however.
