Well that was ok, the whole yes/no thing is a bit silly though, it should have a scale instead.
If they question you over it just say either "You dont get homework when you get a job so why should you at school?" or "Why dont you teach me this in class? Or are you too lazy?"
Seriously, your parents pay for your education and 3 hours of the day you're having to do it yourself. They should be paying you.
*puts away the birthday cigars* :/
But if you wanna do it all at once it saves you spending money later
The only thing I can see you running into is paint costs, I dont know about there but here the paints are insanely overpriced for small amounts.
