Drexel is pretty wonky for many of us.
Best I've ever gotten is about a 40% success rate. Read through previous pages and posts if you want, but basically, MANY people have encountered problems with Drexel.
Whether it is due to the imagesearch thing, or timing, or whatever, it's just wonky.
Cannot remember for Zosha, but not sure I've had much success there either.
