Practice Problems
In the past these practice problem generators have served as opportunities for extra credit. This is not the case for the 2009-2010 school year. The reason that extra credit has been eliminated is because all assessments, with the exception of laboratory performances, are converted to a 4 point scale and then back to a CR equivalent grade on the 100 point scale.
To see the 4 point scale conversion sheet click here.
Note: RAW score is the student earned grade, 4 Point Scale is the equivalent score out of 4 points not 100, and the CR scale is the 4 point scale converted back to a 100 point scale where 4=A, 3=B, 2=C, 1=D, and 0=F. It sounds complex. It's not. And it's extremely beneficial to you or your student.
