ABSOLUTE GARBAGE

Should be free...it is so basic & unprecise its useless...even the game mode of this fails to operate effectively, the game indicates if player scores 50% or higher you progress but this is not true i cosistently score over 30 of 50 on the first three tests but it DOES NOT progress... Its funny because i bought the app to learn what i do not know yet its "rules" dictate i must know before i can even learn????!!!!??? If only app designer had enough sense to grasp this very basic concept!
