I did the GSEC first. It is 180 questions, and you are given five hours. I got 170 correct and finished in an hour. Then I moved on to the serious one. The GPEN is 150 questions and you're given four hours. I got 136 in that one, and again finished in an hour. I actually only had ten wrong, but the java-based connection to a virtual machine was so slow that I just guessed on those because I had clearly already passed.
I do like that they tell you whether or not you got the previous question right or not, so you always know where you stand. I'd gladly give up the ability to review for that. I do find it humorous that they end the exam immediately if you ever get to the point where it's no longer possible to pass. Plus, I imagine it helps maintain the integrity of exams.
The questions were probably more straight-forward than any other exam I've ever taken. I wouldn't recommend challenging these unless you're well versed with the material. I've already done MCSE:S, Linux+, CCNA, CWNA, CWSP, etc. I've also gone through everything for the OSCP and CISSP, and regularly do pen testing, IT audits, risk assessments, vulnerability assessments, social engineering, etc. Needless to say, this was basically all review.
I might challenge the GWAPT next since I've been dabbling with web development since I was 13 and am familiar with all the common attacks. I might have to get the courses for GCIH and GCIA since those are further outside my realm of expertise. I'll see how I feel after I get through Counterhack Reloaded (supposedly close to the IH material) and the new Wireshark book. A quality Snort resource or two should put me in pretty good shape. I'm hoping to make a GSE attempt in the fall of 2011, and getting all those under my belt will make me eligible.
I'll worry about that later though. I only have a couple weeks to prepare for the CISSP, and I'm not even through the AIO book yet...
I didn't really get to prepare for these since I was so busy with work, so I never got around to taking the practice exams. I've already given one of the GSEC exams away, but I have one more of those and both for GPEN. My expiration for taking the GPEN was April 3th, and I'm not sure if the practice exams expire then or not. You must be an active/contributing member to apply. Sorry, no lurkers
Edit: GPEN practice exams are good until 6/2/2010, and GSEC exams are good until 9/22/2010.
