Wording is wrong, lights questions unfair
Example: several flip cards show stern AND sidelights that you shouldn't be able to see in real life, even exactly at 112.5deg relative aspect. Have lots of officially approved paper flips cards and have never seen this before. If you're a beginner then don't use this as you won't understand where the errors are and will end up very confused when you come to your exams - or worse when navigating crowded seas at night for real.
Secondly, the wording is very poor and not precise. The answer to one of several being along the lines of 'a tug boat smaller than 50m with a tow smaller than 200m, skewed to port'
Official terminology should be more like 'Power Driven Vessel, less than 50m in length, underway, making way, towing, with the total length of tow less than 200m, observed from a port aspect'.
If you use this type of confusing and frankly incorrect language to try and pass any exams, leisure or commercial, you will not pass.
Disappointed.
