It seems you have another day. This was in my inbox this AM.
..........Originally, the last day to sign up for the exam was today, March 31st at 11:59pm. The GBCI.org website went down, so they've extended the exam registration (for the current NCv2.2 and CIv2.0 exam) until tomorrow, April 1st, 11:59pm. If you visit the usgbc.org website, you can see this information on the front page.
Just to be safe, I would try and register today (if the website comes back up), just in case the same thing happens tomorrow.
Please pass this on to anyone who you think may want to sign up before the deadline tomorrow.
Thank you for your support of intheleed.com, and I will continue to provide you any important news you may be interested in regarding LEED.
Kindest Regards,
Pat Flynn, LEED AP
p.s. As a reminder, the reference guides for the LEED v3 are now for sale on the usgbc.org website.
Cheers!
