At first, I shot 5 videos.
And today, my students took the test.
These videos were viewed 225 times per video before the test.
This means that they(143 students) have learned almost all videos.
The level of the test was almost the same as usual.
The average score on the test was about 70 points.
It's almost the same as usual too.
Therefor, it can be said that my video lessons have catched up with the usual lessons.
I have beaten COVID-19.
