Hi, @Mel.ea I still have mine. My friend who just passed the board last year mentioned that it has no expiration but I don't know what will happen if you lose it. Also, one of her co-reviewer is a graduate from the '90s around 1995 if I remember it right and that person was able to pass. Just not sure if she/he still has the cases. I suggest you reach out to PRC. Hopefully, in God's will I can pass this year and all of us for sure. AJA!
