I who am that study it freely now. I seem to have done the thing called the free study in an elementary school. (I whom I know am going to make a chair.) However, I do not advance at all. (I chase it, and the plans in particular do not understand at all) which changed school before (studies because I do not do it at school.)
I understand it, but I write a plan at least, and the others are almost amateurs to some extent.
By the way, even oneself does not understand whether you can do it
