Mr.Cortez's Honors Chemistry is a very difficult class. Even if you pay close attention in class, read, and complete homework/labs, you still may fail the tests. (But probably pass the class.) His tests are VERY long and complex. I hate how he grades tests; some parts count 80%, others 5%, and the longest section may count only 15%!!! But sometimes he just gives you whatever grade he feels like, (e.g.; taking off VERY different amount of points for students who wrote NEARLY the same thing). bleh
You just have to get him, if you don't get him then you have a problem. He uses weird analogies, you have to figure things out on your own.
