Well, the eraser smudging wasn't in my favor. Within 4 hours of requesting it, I received notice that the scoring machine was accurate. No change to my score. Looks like i'll be back in NRG come October. BTW, I took the in residence Testmasters course in Houston. It was really helpful, but there were some areas I felt could've been more detailed. They do allow a free retake of the course, though. It helped me stay consistent with my studying. I just need to work on timing. I slowed down a lot during the PM portion.
If the re-scoring stats show that it has never changed a score, I'm curious to why it's offered? Is it because they have to allow candidates the option because of a possible electronic system error? It's easy money for them, that's for sure.
