Hi! I have some dillemas with 3 questions at "Test yourself" section at Aids to Navigation.
One question is that: "On which side should you pass this buoy?" In image is shown east buoy.According to theory in cardinal marks,it says : "These marks indicate which side of the buoy you should steer clear of."
So,if I respond with the opposite and I put west side(to pass this buoy) , it says is incorrect answer,and the correct one is east side,and isn't logical for me. I think could be better if the platform shows also the correct answers when you are wrong.
The second one is "When you are sailing to the sea from a harbour in USA, and you are in the fairway the buoys on your port side are…"
According to theory from IALA B, the right answer should be green cylinders,but it's marked as a wrong answer.
And the last one is this : "On which side should you pass this buoy if you want to stay on the preferred channel? You are sailing in Australia and heading inland."
In the image I have a green-red-green shape and if I answer starboard thinking I have green in portside for IALA B, I get wrong answer.
