Some times it glichis.
By Keya M.
The things that are going well? Almost everything. The only bad thing? Some lessons are so hard, even Albert Einstein had problems finishing them.

Cosmo has helped my child a lot, and has improved her school grades. She is learning how to write her own stories and how to comprehend stories.

By David
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.

My 8-year-old absolutely loves learning math with David! She has been making great progress. David is a fantastic teacher, he's patient, but seems not good at encouraging students.

The Tutoring company communicate information promptly. The Tutors are patient and attentive to the students progress and pace.
