As a senior in the vessel operations class, I've had to go through the chart test that all Juniors have to go through. It's a pretty extensive test that requires the student to really understand the process of taking a bearing, plotting points, calculating course distance, ETA (Estimated Time of Arrival) , and more chart related skills.
A few of the current juniors were in need of some assistance, so some of the Seniors, myself included decided to help them. My take on the situation was to have the Junior I was helping (Leonardo) , actually try to answer a test question and then if he was off or did not understand the process at all, I demonstrated how to do it. An example would be taking a bearing given 2 locations and 2 true degrees provided by the compass on the chart.
