I'm sure there is more to the theory than you have understood. That's why I wanted to ask you a question on the theory to know if you have genuinely understood it.
True, 120 was at 56 last year but I didn't do too poorly in other units. Physics unit 1 is always pretty low. June 2014 IAL unit 2 was also crazy low but I remember that to be quite an easy paper

I'm kinda confused in this question, i thought the answer was related to laminar/turbulent and its relation to speed.
However, In the mark scheme its related to depth of water and drag, could you explain me this?
It's from the June 2015 IAL paper.
Have no idea if I got it right (I think I did), but I remember writing about how there is a lower cross sectional area, and so there would be more more water entering a smaller area which may lead to more turbulent flow and thus create drag.
