Redeeming points for Chinese Help...

It sounds silly, but somehow my wife and I started this system where she'll help me with Chinese if I do more housework. For example, she'll give me a point for washing dishes. I can then redeem that point for up to 15 minutes of Chinese help. So, the two PDF's I uploaded were both reviewed by her so at least I know that I can safely study/memorize them and still be learning correct Chinese grammar and vocabulary.
