Failing tests.... So far in my honors pre-calc class we have taken 3 tests. My grades on these tests have been 57%, 73%, and 63%. i understand all the material in class and have no problem on the homework, but when i take the tests i get so nervous i rush through the test and i make stupid mistakes (like not simplifying all the way, or not factoring completely) this leads to a bunch of small mistakes. Small mistakes individually, but when added up they make me fail. I try to take my time on each question but the time that i have in class doesn't allow for you to look over it with great detail. How do i stop myself from doing stupid mistakes?
