I know about the company and their products/services but haven't used any of their services except probably for their Eureka Math (Elementary grades for the kids). I didn't bother with their English or PhD Sciences options either. It seems A-Street likes what they see and are investing in them, to focus on student learning solutions, and for the acceleration/expansion of the company offerings.
