There is a similar Self
Test question in K&B 1.5 (p. 305).
I too would like to know any kind of trick to speed up the time needed to solve this kind of problem. I got the problem right, but it took at least 15 minutes. That�s with pencil, paper and no stress. I just tried it again watching the time and it still took me 8 minutes to solve. That�s 8 minutes to solve a problem I had solved not that long ago, maybe 5 days ago. If there�s more than one question like this on the exam I feel I am doomed.
