Yes. You may return a study guide within 15 days of receipt if you have changed your mind and will not be taking the corresponding allied-health exam. Just mail the study guide back to MedCA at your own expense, and we will refund your payment, less a $10 restocking fee. Please note that we cannot issue a refund for an electronic copy, nor may you return a study guide after taking an exam or a study guide that has been written in.
