CAH you SEE this in necessary.

The CAHSEE is an important test. It determines whether you get your diploma or not. It shows whether we have actually learned to use the knowledge in school.  It challenges from simple geometry to identifying compound sentence structures, at least from others experience. I think it is an important test because it shows us whether we have done well or we should apply ourselves. It also shows the district and state in which subjects the students need more help in. The reviewing for the test is what is not necessary.
