CASPA has their own formula for calculating GPAs and each program has a different set of pre-requisite requirements. 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 GPA minimum required to apply to a program.  In this service you will send me your transcript and I will calculate your pre-requisite GPA using the algorithm that CASPA uses.
