##subjects to self-study by Yixin

Self-study is a highly valuable skill. The earlier a kid learn to self-study, the earlier we become independent. These subjects are easier for self-study by Tan Yixin:

— piano
— Chinese refresh the new  characters on the post-it
— Weekly English spelling list? I noticed sometimes he could study for a while and know most of them.

We can set a target like “70% correct”.
Target should be achievable not too hard.
Target should be measurable so he can measure his own progress

–math practice problems? Can print out and hand to him a list of problems
–typing? He can practice on his own. There are many tools to measure his speed/accuracy
–Chinese sentence making?
