I left out that damn 'prove that there are two solutions' question, couldnt remember the method even though i covered it last night. Also left out that parametric equations of the curve thing. Other then that, got most of the rest Best case scenario, although unlikely, ~90, worst case ~70.
Edit: for physics has anyone managed to find out where they posted those chaos assessment marks?
