Hello @nsijoro,
A wise man once made a statement and I quoted "If you think education is expensive, try ignorance". Despite the billings nature from the virtual learning apps, one will testify to the fact that it's really helping. Taking canva as an example, creating a virtual classroom can be interesting because the students and teachers will have some sense of freedom. Also, I can say that Steemit is truly a learning virtual institution with cast knowledge to offers. Good luck on your entry👍
