It was really easy but last year's paper 11 was easier in my opinion because I'm a natural at geography/environmental science. I have 1-2 doubts, mainly the fish question. Was it D (black spot below dorsal fin) or C (no black spot below dorsal fin)? I put D because there was one black spot below a part of the dorsal fin. The question was so unclear, they said 'BLACK SPOT' not 'black spots', does it mean just one huge black spot or a small black spot?

Another thing that got on my nerves was the double human circulatory system, I put C.

A, B and D didn't make sense. But the flow of the diagram of C was weird (the vena cava's direction of flow was on the opposite side --->----

Does anyone know what the double human circulatory system question answer is?

Wrong. It gets Oxygen for aerobic respiration from the water, and excretes Carbon Dioxide by respiration which goes out of his skin to the water. So the answer is A.
