So I bought the Set 1,2,3 package from StudISCope for a whopping $109 and figured since I just finished reading Darril Gibson's SSCP book (used only that book), I figured I'd take it to see how I fared up to this point.
After taking the first set A, I scored a 60%. I was pretty sure I got low because of A) the wording of the questions and

the depth of the questions.
As for the "wording", for ex. there was a question that asked about 802.x components and one of the choices was "supplicant system". At first, I was like, "What does that even mean???". Of course after taking it, I had to Google the definition and then seeing that "ah ha" moment, that I already knew that of course 802.1x needs a client end piece. But how about since I didn't know what supplicant was? Are we allowed to ask the proctors to be a dictionary and ask what the hell those cryptic words mean??
Also 1 or 2 questions were really advanced and for sure were not covered in the SSCP book. It was asking about what network protocol would be the fastest to come back if it went offline and it listed protocols like OSPF/RIP, etc and I was like, "uhh this is a Cisco CCNA exam?????!" Another was a "black hole" question and off the bat since I did take CCENT, I knew what that was but for sure was not covered in the book.
I went back to the relevant chapter of Darril Gibson's book and saw no references to any specific IP routing protocols. I surely hope the real SSCP exam is not like this since my test is in 6 days and I will be nowhere near ready if this practice test from StudISCope is any indication to the real exam...
