Early in the planning phase of integrating IMMEX problem sets into your curriculum, previewing problem sets to establish fit with core content currently or recently covered is crucial to maximizing use of instructional time. In addition, advanced planning will enable you to make the necessary preparation for submitting a staging request at least a week in advance of IMMEX implementation and enhance chances of on-time access to computers in the event you need to reserve the computer lab or procure computers from other sources available at your school.
