I have recently enrolled in the senior physics challenge on Isaac physics and I am quite sceptical about few things.
First, do they take into account of multiple choice questions at all? Since you can get them right by just guessing.
Second, I have notice that essential pre-university questions are easier to do than the rest, does that by any chance mean that they will be weighted the same as other questions on the same difficulty?
Lastly, would maths and physics questions be weighted equally regardless of the topics?
Sorry if these questions sound a bit excessive to ask, I did not a things about this challenge before. It would very helpful if anyone can answer any of the questions above. Thank you
