Real Reviews from Real Parents

4.9 out of 5



My 3 sons ages, 10 1/2, 9 and 7 started using Juni in early June 2020 and absolutely love it. The instructors are college age kids and they relate to my boys very well. My oldest is doing both the coding and math tracks and I feel like he will be way ahead of his 5th grade class come the fall. Once the other two are old enough I will certainly be enrolling them in math as well.

Juni has been amazing for my daughter. She is a reluctant learner when it comes to Computer Languages, but the Juni instructors have been engaging to her at a level where she feels comfortable with them and they manner in which they present the curriculum. They understood my ask that I Wanted her to start liking computer languages, and they are presenting the information in a way that is fun and relatable. I am very happy with my Juni experience and my daughter's journey with Juni so far!


I have two boys taking classes and the Juni takes the time to match the right instructor for my children. They are patient and very consistent in their teaching. The boys are thoroughly enjoying their class and love accomplishing and learning new things!
