How exactly would be the best method in approaching them? It is not so much solving them that bothers me, but the fact that I am pressed for time. It becomes infeasible to draw diagrams, free-body/motion diagrams, listing knowns and unknowns, and then starting the analysis to solve 1 out of 13 problems with only one hour left. Any advice on this? How do you tackle problems in exams you've never seen before but yet don't have all the time in the world to solve them? Is it better in those cases to just mindlessly "plug-n-chug"?
