Does anybody know how the PM sections are marked and based on what criteria? There are too many points here. Is it the final answer, the sketches, your hand writing, all the design steps, ..... etc? Do they grade it by marks or just "acceptable" or "not acceptable"? for example if the full mark is 100, 25 per question and you did the first two perfect but the other two are not very good. Will you get 25+25+10+10 = 70 out of 100 for example? OR you must have acceptable in one problem to get its full mark? in this case it will be 25+25 + 0 +0 = 50.
