CHEMISTRY!!

I totally hate chemistry!!! We had a test today, and it seemed like everything that we learned was NOT on the test. I was so mad! I studied like crazy and the test just completely threw me. I probably failed. I try and try to understand chem but i can't. It's just like a foreign language to me that no matter how much i go over it and study i can't decipher. I just hope i don't completely fail the course.
