Hard time

<p>Man O man... My chem teacher gave us chapters 8-20 to study for the Final.
What the hell? Can you be any more specific? jeez... O well, I still have my note card, which I am permitted to use in the exam. But still.....
In my alg 2 class, my teacher goes over 5 problems in the Final review packet and then abruptly stops... She spends so much time talking about things that are COMPLETELY IRRELEVANT (SHES SEXES) ........</p>
