Hi There,
just registered for an exam with Pearson on learning.microsoft.com .
On the exam detail page it says the exam is on Wed 4th Feb.
On my landing page, the summary on the right side of the page says 3rd Feb.
The confirmation from Pearson is definitely 4th Feb.
I assume this is because I'm in Australia and there's a small timezone bug on the summary page.
Let me know if I can provide more information.
