It was very helpful for me to learn English with weekly lessons.
By Kenyon C.
First, of all my teachers are the best teachers!!!!! Secondly, my classes are fun and easy to learn sometimes when I don't know I ask them what they mean. Lastly, I think anyone who wants to learn should use Cosmo to understand more and they help with your homework (which helps my grade a lot!!) I want to thank my teachers Shyloh and Aaron for helping me improve my writing and reading.

Cosmo has been fun and interesting. My teacher, Mr. Eric gives me choices, but makes sure I get the amount of learning we need. I have learned so much from when we started. Thanks Cosmo!

My teacher is very nice and the material helps you learn a lot of skills. Definitely recommend this for others who want to strengthen their ELA skills

Most of it is good, the teachers do teach well. Still, there are too many notifications. Also, the Cosmo app tells me to keep persuading friends to join and I don't know how.
