GPM, just for your reference, all CFA Examinations are out of 360 points. One point for each minute it should take you to answer a question. This problem was worth 2 points. Keep in mind that they may give credit for an explanation even if you circle something else. Assuming that you received no credit on your explanation then this adjustment would be .5556% points (2/360). If they had previously given credit on the explanation but not the answer, then this would be approximately .2778%.(1/360).
Caratop1999-True on 360, I made a mistake allocating each part an equal piece of the total 21. But the part of problem that was changed was not worth 2 pts on the 360 scale, it was worth 6. If you circled and justified the wrong answer (later changed to be acceptable) you would have intitially received zero credit. There is no way you could have received partial credit b/c you would have circled incorrectly and justified an incorrect answer. 6/360=1.7% additional on the total exam.
