Absolutely buzzing right now! Edusum.com was a total lifesaver for my GIAC Open Source Intelligence prep — I just walked away with a spicy 82%, way above the 69% pass mark. Not gonna lie, topics like OSINT methodology nearly did my head in, but the practice exams broke it down so well I actually started enjoying the grind. As someone who’s already deep in the open source game, it’s rare for a prep site to still surprise me, but Edusum’s mock tests legit felt just like the real deal. Got to say, the unlimited attempts feature was a complete chalu move (shoutout to all my fellow hustlers who know the value of a good repeat!). Each session made those tough syllabus areas less intimidating, and I could literally see my scores climbing.
