The PELLETB is California's entry-level written test. A T-score of 50 is average. One score can go to several departments while it is still valid.
The dark band is a passing score. Hatched rows use a different test or do not publish a T-score. This checks the minimum only. Departments rank candidates, so a higher score still helps.
We have not tested the paid courses and are not paid for these links. They are the two sellers other applicant sites point to most.
