Things I Think We Should Know For The Chem H Test

I never thought it could get worse than Bio H with Grunder.

Until i joined...
A' Chemistry H

with MISTER. Dinh

I think we need to know these things for the test...

I got a lot of these ideas from Byron's study guide.




Does this feel like a final exam to anyone else??




Feel free to add any other info!

Good Luck Ya'll!
