I don't have a drawing to post for today but I do have some advice. Don't study for ten or eleven hours in a day. Definitely not without taking breaks. I'd been working on math all day today since 11 am. I went to do my home work, the part that I actually get graded on, and I kept having to redo some problems. You get more than so many, I don't know how many, chances to answer the problem right. My brain was turning to mush. So I quit for the night about 9 pm or a little after. I'm planning on doing three blog posts this week, at least. I'll probably do the third one tomorrow. And I'll see if I have a drawing to post then.
