Hi @melvinvox​, you'll be required to take the exam again if you wish to receive the FME Certified Professional accreditation. A score of 80% or higher is required as per the certification page: https://engage.safe.com/partners/certification/fme-certified-professional/

If you have any further questions during this process, I highly recommend reaching out to fmecertifications@safe.com. They'll be able to provide more concrete answers to your questions.
