You are on the right track. Self belief will get you there in the end. Despite Northern Sky's jaded grumblings, you know commercial flying's what you want to do, warts and all.
The CPL/IR is hard work, but get through it. I don't think exam results are worth that much in the real world, just try to get them out of the way asap, as its that part of the course that saps most poeple's enthusiasm. Make six months sacrifice of your whole life just to get rid of them, and then the fun will really start.
Don't sweat it - just remain a believer!!
