According to the CFA
Institute, a CFA Level 1 candidate can withdraw from his or her current CFA examination (no later than one day before the exam) and re-register for the next CFA examination - once his or her withdrawal form has been processed - by submitting a new enrollment form.
Since it will take 7-14 days to process your withdrawal form, the CFA Institute indicates that you can shorten the time to re-enroll in an exam by sending both your withdrawal form and your re-enrollment form and fee payment at the same time. (Both in paper format.)Click here

You will not be refunded your original fees paid; however, you will only be required to pay the enrollment fee for your newly scheduled examination.
Note that if you miss your exam or do not properly withdraw from the examination, you cannot re-register for the next CFA Level 1 examination until results for the exam not written are released. Since the first registration deadline for the CFA Level 1 examinations is typically six months in advance and results for the missed examination will not be released for approximately two months, you could end up having to pay a high enrollment fee. For example, if your exam was scheduled in June and you did not withdraw officially, you would have to wait until the end of July before you could register for the next exam, which would be in December. Since the first registration deadline for the December examination is usually in March, you'd have to pay the fee required at the second registration deadline, which is usually in August.
