So if you are still wondering when the pants will change, I can predict that it MIGHT or MIGHT not change until Pearson VUE and GMAC fix their online grading system. If took the test during the week of Jan 7th to Jan 12th then you probably received an "score fulfillment" email the week after, but no score report was attached and no score was showing online. I called Pearson VUE and GMAC and they told me they are having technical difficulties with their online grading system and I need to wait for 20 FULL days to receive my official score (i took it on jan 11th).
For those who still remember the December pants changed on Dec 27th, GMAC sent out an email by accident to inform students about additional testing on the 27th and they changed the pants on the 27th. Maybe this month they are just waiting to fix their scoring system before changing the pants. So if you are taking it this weekend, you might be safe. If you are taking it next week, then you might be running around naked.. I could be wrong!
