Ratings and reviews

I wasn't sure what to expect from this app, but at the end my 9 year old son asked when we would be doing another class! The whole class is a 1 on 1 session with a teacher following a really fun and interactive story line by Cosmo! It was so well done my kid really enjoyed it!

Very disappointing experience. Their “progress report” calls often turn into sales pitches for more classes. Learning Partners change frequently, communication is difficult, and new partners seem unaware of prior arrangements. We signed up for one class per week, but they mistakenly booked two. When I asked them to cancel their extra booking, they said I would lose the credit due to the 24-hour policy and would need to pay $10 to use it later. Customers should not pay for the company’s schedulin

My son is in kindergarten and is improving and learning a lot with his teacher Alina and Marissa, they are great teachers, sweet and knowledgeable all we need for our son. I will keep investing in my son with Cosmo. Is perfect, Is individual tutoring with kid, the app is easy to use and has all the tools we need as a parent to review and learn. I am very happy with Cosmo.
