Yes I was informed that there might be a second test later on this year, but I'm yet to hear more. I'm nearing the end of my 4th waiver now having stupidly wasted the first two when I wasn't aware of the KSP waivers/rules/the impact it would have. My 4th waiver expires early next year, so hopefully I'll have sat and passed the exam by then, if not, I guess we will find out. It's not much fun being in this position of constant worry that's for sure.
