Yes. Whether you are challenging the exam or not, you will get 2 practice exams bundled with your certification attempt. The practice exams are very much true to the actual exam from my experience.

It's $99 USD per practice exam (in addition to the two you will get).

People...I passed my GPEN exam. 

Things that came handy for me are

1) various cheatsheets on the SANS website
2) Counter Hack Reloaded

Other resources that I referred to and had got my notes from
1) Penetration Tester's Open source toolkit
2) Metasploit toolkit & Offensive-security
3) Webcasts from Ed - CoreSecurity and Pauldotcom website.
4) Cmd Kung FU Blog

My lab
1) Used pfsense VM image as a firewall to separate my internal and external network teams
2) Target machines - Ubuntu, Windows XP and OWASPBWA VM
3) Attacker machines - backtrack and win xp with as many tools supported

I purchased 1 practice exam and the 2 free practice exams helped me gauge my weak areas and where I needed to focus.

Last but not the least - this forum and its members. I wish i had discovered this site earlier in my career.

Cheers

Congratulations sachitre!

Did you also take the 6-day course or you just studied on your own?

Congratulations!!!

Congratulations and thank you for the info.

The last 10 questions (I believe) in my exam involved me connecting to a virtual lab via a Java app to use tools/perform attacks to get the information necessary to answer the questions. It took about 5-10 seconds for the screen to refresh with the smallest amount of information, so I just skipped them and guessed at those remaining ones. You didn't have that?

I didn't expect there to be overlap between the practice exams and the actual exam. I guess what I was asking was, did you feel it was worthwhile to buy the additional exam, or was it a lot of what you already covered in the other two?
