Does anyone else here think that the assembly question (C-5) takes far too long to complete properly ? I've practicied a good few from past exams and can never finish in under 35 minutes. Is there some sort of method you must use to be able to do this question within the time constraints of the exam ? Would I be better of doing question C-3, 'Surface Geometry' instead ? I've actually tried a few of them and they seem far more doable. All help is much appreciated !
