You have stumbled into my semester two section. Way to go. You can click a mouse button. Click even more and you may find some notes I took on semester 2. I know what you are thinking. Why is there no chapter 1? Haha, with all due respect (none) you are an embecile. Chapter one is review. Now me and my nerdy friends (my pet cactus Edward and my pet Vine Broom Hilda) will laugh at you.
