I am curious about the purpose of this exercise. These are exam questions where I suspect they come from different years and students have been complaining how much harder they have become. I voted both A1 and B1 as the easier thing to do, but only as "probably" because I can imagine that students see that differently. A1, for example, has more standard questions, and B1 gives more guidelines as to how to proceed. My own experience is that "easier" questions, those with more hints and simpler calculations, give worse marks, because it makes it more certain that good students score well, whereas bad students struggle as before - the result is a "camel" distribution of marks that is harder to re-scale. (This may be off the point of this poll, of course.)
