Hi non-trads,
I just wanted to make those of you who are studying for the MCAT aware that we have an MCAT help subforum on the Student Doctor Network (SDN). There are explanations threads that contain posts with tips and info for each subject, and questions threads for each subject where you can ask for help with topics that are giving you trouble. Several of the volunteers, myself included, are non-trads. To view the forum, go to the MCAT Study Questions Q&A. You do not need to join SDN to read the subforum; however, you will need to register if you would like to ask questions or post on SDN.
If you’ve already taken the MCAT and would like to volunteer to help answer questions, please PM me here or on SDN. We’re always looking for new volunteers.
