Hi all! I'd be happy to jump in on a few of your questions. I just sat for the online exam - it was an experience, for sure!
While I've reached out and have not yet heard back from GMAC, the proctor was not aware of whether or not writing aids such as the use of a touchscreen or an external writing tablet are permitted. In general, the proctor is only aware of Pearson-specific policies. Anything GMAC specific needs to be fielded GMAC's way. (I'll let you know as soon as I hear back from them - though others may have thoughts or GMAC-specific responses!) I know a few have reached out and received seemingly-conflicting responses on the note of touchscreen use/etc.
Scores are not immediately released. The prompt mentioned a time window "within two weeks," though I know other sources on MBA.com cite a shorter window (7 business days, generally).
I would also mention for those taking the online exam soon that there were some glitches associated with the online whiteboard. Nothing major - but I did occasionally have an "enter" delete my text rather than move to the next line, etc. I've reached out to GMAC on that note as well.
The sections definitely required some approach adjustments, and anyone preparing for the online portion will want to know ahead of time how they plan to approach the use of keyboard vs. mouse tool, etc. There are also some strange nuances with the geometric figures/etc. that are worth noting (spaces have an automatic "fill" of white, etc.)
I unfortunately have to scoot right over to a tutoring session post-test, but I'll be running a webinar on the Veritas Youtube page tomorrow at 8pm eastern if anyone wants to jump in and ask any questions/hear my thoughts on how to make the best of the format. (I know that falls at a somewhat funky time for many of my GMATClub friends around the world - so feel free to leave a comment if you miss the live stream!)
If you have any questions, you're more than welcome to tag me here as well, and I'll try my best to hop back on the thread and get to them
Best of luck to anyone braving this format over the next few days!
