NCCCO Core written exam: a 7-day plan for the last week
The last week is for sharpening, not for learning a whole outline from scratch. The aim is simple: find what still costs you points, fix the two or three biggest leaks, and arrive rested with your pacing practiced. This plan assumes you have already studied and have a test date.
The format facts come from the current NCCCO Mobile Crane Operator candidate handbook, cover code MCO CH REV 01/25, at nccco.org: the Core is 95 questions in 90 minutes, no calculator, in four domains weighted at about 22% Site, 28% Operations, 23% Technical Knowledge and 27% Load Charts. Check the revision code on whichever handbook you use, because older ones differ.
If you are starting from zero, this is not the plan for you. Use the 8-week plan for people new to cranes instead.
Before day 1
Gather your misses. Every wrong answer from practice goes on one list with a tag: Site, Operations, Technical Knowledge or Load Charts, plus the reason. Reasons are usually one of four: did not know the term, misread the question, missed a chart note, made an arithmetic slip.
Count the tags. The top two reasons set your week.

The seven days
| Day | Job | Time |
|---|---|---|
| 7 | Timed set under exam conditions, no calculator, then sort every miss | 90 min |
| 6 | Fix the biggest leak from day 7 | 45 min |
| 5 | Load charts: full problems end to end, by hand | 45 min |
| 4 | Second leak, plus a signals or terms pass | 45 min |
| 3 | Second timed set, shorter, to check pacing | 45 min |
| 2 | Redo only the questions you missed twice | 30 min |
| 1 | Logistics, light review, early night | 20 min |
Adjust times to your day. The shape matters more than the minutes.
Day by day
Day 7: the timed set. Do a full-length set at one sitting with no calculator. 90 minutes for 95 questions is just under a minute each. Do not look anything up. The point is an honest map.
Day 6: first leak. If it is vocabulary, read the crane terms glossary and say each definition aloud. If it is a topic such as stability and side loading, read it once, then answer questions on it.
Day 5: charts. Load Charts is the heaviest domain per task. Work whole problems, not lookups: choose the chart, find radius, read gross capacity, subtract every deduction. Use the load chart practice tool and the routine in how to drill load charts. Do the subtraction on paper, as on exam day. For hand arithmetic tips see load chart math without a calculator.
Day 4: second leak. Same method. If signals are the problem, run a short drill of the standard signals.
Day 3: pacing check. Do half a set against half the clock. If you run over, the fix is usually to skip and flag long chart problems and return to them.
Day 2: repeat misses. Only the questions you got wrong twice. Explain each wrong option aloud. If you cannot say why an option is wrong, you do not own the idea yet.
Day 1: stop studying hard. Check your booking, ID and the rules for your test center or online session, using what to bring on exam day. Review one page of notes. Sleep.
What to skip
- Learning new reference books. A book you have not opened by now will not help in seven days.
- Chasing rare topics at the cost of chart practice.
- Cramming the night before. A rested mind does hand arithmetic better.
- Hunting for recalled exam questions. Real exam items are confidential and the ones online are often wrong anyway. Original practice with explained answers is the better use of time.
If a retake is on the table
No plan can promise a pass, ours included. If it goes badly, there is a waiting period before you can retake a written exam, and what to do after a failed written test turns that gap into a targeted plan. The cost, retakes and 12-month window guide has the current timing.

FAQ
Should I do a full practice exam the day before?
Most people do better with a light review and sleep. A full timed set that late can leave you tired and shaken by one bad result.
What if my weakest domain is Site or Operations?
Use the same plan. Spend the leak days on that domain. Because Load Charts has only five outline tasks at about 27%, keep one chart session even so.
How many practice questions should I do this week?
NCCCO sets no target number. Quality matters more: every miss should end with you able to explain the right answer and each wrong option.
