There is no need to prepare for the exam. The comprehensive exam covers topics taught throughout the degree program, which are aligned to the topics required for accreditation. If you are taking this exam early in your program (the inbound exam), there is no need to prepare. The inbound exam simply assesses the baseline data the school needs for its analysis. If you are taking the exam at the end of your program (the outbound exam), the preparation for the exam comes from your educational experience through the required courses for your degree.
