I took mine on Saturday and other than a slight hiccup in getting the "artwork booklet" (the staff could not find the box of booklets for about 15 minutes), everything went smoothly.
I showed up 30 minutes early at 7:30 for the 8am exam. Bought my references in my tote bag and my rulers and calculator. They give you a key for a small locker and ask you to put away everything except for your references. They even asked me to take off my watch. That's fine, the computer you're working on has a clock in the corner of the screen.
They provide you a "artwork booklet" (as describe by other people already) which has the figures you need for the exam and also some randomly spaced blank pages you can use as scratch. They also provided two lead pencils (not automatic, just regular pencils).
The desk is a bit small compared to what we had during the April CA exam, but I only had two small reference books so I thought it was enough room for me.
The computer based exam is pretty easy to get a hang of. As you work through the questions, there are buttons at the bottom that let you navigate back and forwards to questions. There's also a button called "Mark" which lets you mark the questions for review at the end. So I just used that to flag all the questions I wasn't sure about. At the end (or at any point you want during the exam), you can go to a "review screen" which will list all the questions you've done and show which ones you've "marked". You can then click "review" and it will let you quickly click through only the "marked" questions. And you can "unmark" them as you work through and are satisfied with your answer. Very easy.
The only thing which tripped me up initially was that the very first line of the question would sometimes refer you to a figure in the "artwork booklet". And I read the questions so quickly, that once or twice I missed that line, and then was confused as to why I couldn't get enough info to solve the problem. These I "marked" and only realized my mistake of not looking at the figure on my second review. Also, it seems like you should use ALL the figures in the booklet. If you finish the exam and haven't used ALL the figures...you probably missed a question.
Overall, I thought the exam was fair, relatively painless, and that the Prometric staff were nice and efficient. True, my test center had a bit of a hard time at 7:30am locating the test booklets, but by the time I was ready at 8am, they had found the booklets. They very nicely apologized for delaying my start (you can start as soon as you get through their setup, even if it's earlier than 8) and I got all 2.5 hours to work on the exam.
Although I was very upset by what happened in April, I am pretty pleased with this solution and so so happy that it's finally done! Good luck to the rest of you!
