Chemistry quiz

I got 17/20. An OK mark, right?

But I still feel disappointed.

Why are the guys in my group so good in chemistry? I marked one guy's surprise-test paper, and he got full marks. Then yesterday's quiz, a guy's quiz paper -- he got full marks. 20/20.

And I got SEVENTEEN!

D:

Just because I wrote one hydrogen atom instead of two. Oh, my chemistry is rusty. Not my best subject back in high school, either.

Hah. Oh wells. *shurgs*
