CASPA has their own formula for calculating GPAs and this does not necessarily match the GPA that your university/universities may have calculated. For example, CASPA does not include medical terminology into the science GPA whereas some universities do.  CASPA calculates your GPA after you have formally submitted your application.  This can be problematic because you may need to know your GPA as CASPA will calculate it to determine if the you will meet the minimum required to apply to a program.  In this service you will send me your transcript and I will calculate your science GPA using the algorithm that CASPA uses.
