How far down is down? If you are still above 75%, or so, you will be fine. I love this metaphor: you can't play tennis with your eyes on the scoreboard. Just keep yourself focused on what keeps you excited to learn. This process isn't just about passing a test. I believe, you should feel empowered every day by it. You have plenty of time to retain all the information you need for passing, I promise! Turn this around and use this as a time to see yourself as already succeeding, as already having the certification. See yourself as the committed, competent, excellent nurse that I know you already are.
I'm sorry that it took a couple of days for me to answer your post, I've had a tough stretch!
Hang in there...you can do it.:yeah:
