And the main reason there are huge numbers of students who are struggling... Is because people insist (like myself) on enrolling in things like Maths or Chemistry or Physics at University without having studied such things in High School. My background is in Philosophy and Psychology... I am used to thinking that University is fairly independent from High School. Going over to Maths... Engineering... Chemical and Physical Sciences, in particular... Is like another world with respect to the progressively (plodding, for many) cumulative nature of them.

Different Universities will be different with their different entry requirements and (I've learned) there is a world of difference between a first year course like 'physics for bio-medical science' or 'physics for sports science' or 'physics for majors who intend to continue on with physics'. I'm not ready for the later, yet. Need a calculus course first... But, hey, calculus is just some extra tricks on algebra and my algebra tricks are coming together...
