I highly recommend Novakid
I have been using Novakid for my two children, 9 and 6, for 4 months now and I am really satisfied with the results! It's amazing, my children have learnt much more in 3 months with Novakid professors than what they did at school. The B2B system is very efficient and the playing lessons attractive for kids. They are happy with them! Standard teachers are very good! I highly recommend Novakid because it's adapting to the level of the kid!!
