I also sit for boards soon. I have 600 questions left to take, that I probably won't finish in time, but I am sitting at 63% overall, 87th percentile. I took the readiness exam today and got 60%, 60th percentile, very high chance of passing. Fingers crossed!! I am SO nervous. I will update when I take boards and let you know if I passed/failed. Good luck to you!! You got this!!
