This post is only relevant for physics SL timezone two people. The truth is that proton coming into electric field question was wrong. The command term in exercise was “calculate”, there is no way to calculate without having speed, for all the people saying you had to do it in terms of v, thats not what term calculate means. Also atleast my impression on the exam was that it was harder than past papers. There were a lot of tricks in the ballon question, having to subtract electrons to get binding energy of nucleon, also theory isotopes etc, generally most of the topics were the ones that people dont really understand that deep, thats just my impression what are your thoughts and predictions for grade boundaries.
