I passed Environmental first time. I thought the morning was pretty straight-forward, but I was nervous about the afternoon session since it was a lot of qualitative questions about things I'm not so good at. I have always been weak in air and water distribution systems (which is why I work in remediation). I studied for about 100 hours, tried to get 10 hrs a week starting in mid-February. I read the EERM cover to cover and worked the corresponding practice problems for each chapter. Then I did practice problems every day until the test. I had to take a break the week before the test because I got the flu and could barely walk, let alone study.
Test results came in today, which also happens to be my birthday. Best present I've received in years.
