I love that it's easy to use, has great features for both students AND teachers! It is very user friendly which makes learning fun & interactive!! The best thing about this program are all of its different levels so there isn't anything you can learn in one class where another student cannot see or understand what they're doing wrong (or right).
There really aren’t any downsides at least not ones i have experienced yet anyway :) This would be my number 1 choice if your looking into digital programs because as far back like 10 years ago when we had computers only used by adults who were professionals etc., now everyone uses them just everyday life even kids/teens do their homework online with these types things instead paper work ect..
