@csk21 There is no attempt to mislead or confuse the examinees on the FS exam. Things change over time and referring to exam prep material from 10-15 years ago or older will be only minimal help in preparing. Test plan specifications change every 5-6 years not to mention the format for how the exams are delivered.
I don't believe they intend to mislead or confuse. They do intend to test your ability to see through the smoke and haze and to understand the true issues at hand. There may be a lot of peripheral information given which has nothing to do with the answer.
Maybe mislead and confuse weren't the right words to use...regardless of the terminology I noticed that the more recent exam took more time to visualize and understand what was actually being asked.
