Tests are graded in the usual manner. There are at least two tests and comprehensive final. Small tests may happen unannounced, or they may be only announced through e-mail. Those with the best scores get an A. Those with lower scores will get a fair distribution of grades, but since the tests are not standardized it is impossible to determine a percentage point used to determine each grade. Tests will have both a factual component and a thoughtful component.
Most students do well to form a study group to quiz each other over factual material.
Additionally, such a group is a good way to discuss options for the thoughtful situation questions . Good teachers solve many classroom problems through discussions with their peers. Plan and teach your field teaching sessions the best you can. Again, a partner or planning group is useful. I have put down some things that have worked for me to get better test grades when I was a student.
