Sylvan had some problems with VFP Beta Exam registrations last Friday. They had the 155 and 156 exams mixed up. Bottom line is, if you think you registered for one, you may actually be registered for the other. Call Sylvan and verify your registration. Also, based on my experience with Sylvan, call again the day before the exam to verify again.
