When Should I Register for the Usmle ?

Although there are no deadlines for registering for Step 1, you should plan to
register at least six months ahead of your desired test date. This will guarantee
that you will get either your test center of choice or one within a 50-mile radius
of your first choice. For most U.S. medical students, the desired testing
window is in June, since most medical school curricula for the second year
end in May or June. Thus, U.S. medical students should plan to register before
January for a June test date. The timing of the exam is more flexible for
IMGs, as it is related only to when they finish exam preparation.
Choose your three-month eligibility period wisely. If you need to reschedule
outside your initial three-month period, you must submit a new application
along with another application fee.
