Well I can only congratulate you for signing up for the massive content (and pain), that you will receive in return  I have been very satisfied with Offensive Security, and all their courses are of a very high quality! 

Don't forget to check out their IRC channel at irc.freenode.org #offsec , in case you're not already there 

Comes with the territory (getting stuck, sometimes.)  Just stay with it.

Would like to provide an update to all. I got stuck in the buffer overflow module and didnt progress further. I am gonna work on creating some exploits locally and then continue my lab access. As the wise men said, "Try Harder".

I actually took (er, am taking) a detour here to refresh my C knowledge and learn assembly. I think the material in the course is enough for me to fumble through the examples, but I really want a more in-depth understanding of how this works. They do some of this in the free Metasploit Unleashed course too, so be sure to check that out if you haven't already.
