Great idea to help kids ,teachers and parents as well I tried first free offers which is limited access for valuations of contents being provided by KD
Lots of innovative methods used by experts to learn if seriously taken into consideration
My kids school teachers insisted us to take help to learn and keep kids busy online library especially social science and science related subjects.
Our both kids under Grade of 4 to 8 which is for middle school standard Later after observing their interest learning their schools works from this platform I subscribed suitable plan.
I also realized they can provide physical text books as test what they learnt ,so reading and writing practices also improved and tested.
