Very insightful post, jdscottPE. Thanks for sharing.
I completely agree, I could work most of the practice problems without even looking at reference materials because I became so familiar with the formulas, concepts, etc. I was scoring in the 90%+ range on CI, Spin-up, Graffeo, and NCEES practice exams. However I am almost certain I failed this exam. I can count at least 15 problems that I remember that I know I missed... after looking them up afterward. Slim chance in hell I missed 24 or less total.
What is the NEMA MG-1? I've tried searching google. Is this a book or table that we should be taking into the exam (in case we have to retake the exam)?
I noticed one of the NEC problems being a bit "off" as well. Or having 2 acceptable answers.
I also saw the KVA vs KV error. I'm hoping that problem is thrown out.
Kovz you could still pass, the exam is curved.. I know someone who was certain he missed more than 20 and he end up scoring an 80%. Some questions do have errors and I believe they get thrown out. Last time when I studied for the exam, I answered all the practice exams you mentioned minus the Graffeo and I was scoring in the 90% range too, the problem is I just don't think that covers everything on the exam, and I am sure you saw that yourself. That's why I made a comment 10 days before the test that basically I did all these exams and I still didn't make it.
I think these exams you mentioned cover a solid portion of the test and puts you in the groove of answering problems, but I really do believe that they only cover about 50% of the exam material. I think the best way to prepare would be look at the topics mentioned at the beginning of the NCEES practice exam and make sure you have an understanding on every topic and some material to reference during the test. Usually if you take a class they provide you with notes that would cover all the topics, and that helps during the test. Also, reading researching the internet and printing some related articles and reading them helps too.
The exam was not an easy one. I really hope that we all score higher than the cut score and pass, I know that everyone that reads this thread put his heart into studying and spent long hours looking at books and answering questions. Let's hope we get rewarded for our hard work and find that magical word "pass" next to our names!!
