Once you enroll in one of the USMLE steps, you must complete all the other steps in a seven-year period. There is no limit in the number of attempts per step, but you can take the same exam only three times in one year. If you take one of the steps and fail, you can apply immediately to retake. Don't forget that once you pass one of the steps you cannot retake it, your score will remain permanently in your record unless you wait for the expiration of the seven-year period.

You can reschedule your exam date as many times as you want and pick any available day as long as it falls in your eligibility period. Although, you have to reschedule with enough anticipation, otherwise you will have to pay a rescheduling fee. To avoid a rescheduling fee, your change has to be made at least 5 business days before the day of your exam in the case of USMLE steps 1, 2 CK and 3; and 14 days in the case of USMLE step 2 CS. To reschedule just follow the same steps you did to reserve your first appointment.

If you can't take your exam during your eligibility period, you can apply for an eligibility period extension, for which a fee will be charged. You can request an eligibility period extension only once. In the case of the USMLE step 2 CS, if you don't take your exam in your eligibility period and it expires, then you must reapply and pay again for your exam.
