So I called on hour 52 to reschedule my exam for after the holidays. They then informed me that the 48 hour rule is actually the 72 hour rule to push your test date back, so I'm locked in for thursday. I would be forever indebted to anyone with series 3 willing to sell.
You can order a book through Amazon. I just took it. Take the practise test a few times and you should have no problems. There are some wrong answers though.
