Change point system

[RuthShryock]

Point system is currently configured in a way so that a total of 8 out of 10 points must be earned in order to advance. However, it does not matter how those points are earned as the child can score 6/10 and then answer one more question the next time they play and advance.

Change this system so that the child must earn 8/10 on the CURRENT attempt (basically the score shouldn't accumulate). This helps the kids really master the different topics that they are learning.
