To pass the exam, I need to get at least 75%. I went in with lots of confidence, but exited with a lot more humility. There were some tricky questions, not looking at the big idea, instead asking for minute details - and 2 questions on electromagnetic fields. Really?! It's that important?! They were ones that I got right though.
When back home, I went through the text and the online portion to see if I could locate the information used in some of the questions. I discovered that I had answered some questions correctly and some incorrectly. That didn't help much. I'm hoping that because I reviewed my test answers, I got enough marks to pass.
So now, I wait for a few days before the results are sent to me, probably on Thursday. Jennifer kindly reminded me that I felt this uncertain after the first two exams as well. I'm hoping that my worrying is unnecessary.
Fingers crossed.
