I've got about 6 years running mobile cranes and my employer is pushing me to get NCCCO certified before the end of the year. I understand the process requires both a written exam and a practical evaluation and I'm trying to figure out the right order. Some guys at my yard said written first, but I've also heard the practical can be scheduled independently.
My main concern with the written portion is load chart calculations and rigging math. I'm solid on the operational side from years of experience but those calculation questions don't come naturally from just running machines. I've been doing about an hour of practice daily for the past 3 weeks and I'm around 67% on timed practice sections, which feels low with about 7 weeks left before my planned written date.
I used a NCCCO Practice Test resource recently and noticed the load chart questions are really specific about lift radii and boom angles - more precise than what we typically eyeball in the field. Is there a trick to getting efficient at those calculations, or is it really just reps until table-reading becomes second nature?
Written first is the right call for most people because it expires after a set window, giving you a deadline to schedule the practical. I did written, passed at 79%, then had 6 months to arrange the practical site visit. That sequencing worked well - just don't let too much time pass between them.
For the practical, find out in advance what equipment the test site uses. If it's a machine type you're less familiar with, try to get some hours on it before your evaluation date. The practical examiners are strict on procedure and sequence, not just outcome.
67% at 7 weeks out is workable. The written exam is hard but your experience means you already have the conceptual understanding - it's mostly about learning how to translate what you know into the exam's question format. Most operators I know who studied consistently passed on the first attempt.
The load chart math really does just come down to reps. I did 15-20 load chart problems per day for 4 weeks before my exam and went from 64% to 88% on those question types specifically. Setting up a systematic approach - locate boom angle first, then radius, then rated capacity - makes you a lot faster under timed conditions.
