@Rasha, first off I want to say is take a breath and go have a drink. Smile, laugh and do not allow not passing this cycle affect your upcoming exam performance. YOU GOT IT!
So, now my input. In April '18, I took an failed the PE Civil Structural exam- ~41/42 correct or so if I properly recall. I went into the exam extremely confident as I put in a lot of time studying and preparing myself like so many of us do. I took the exam and felt confident in the AM and defeated in the PM. My results reflected my feelings. I spent too much time on the evening questions... I found myself thinking 'this question isn't too hard... but I need to search to find this one aspect'. 10 minutes later, I would be unable to find what I was looking for and realize I wasted a lot of time in doing the search. I had around 8-9 questions remaining when the 5 or 10 minute mark was called. The scramble was on. If you look at the exam specification, the last 6 questions are Codes and Construction questions. I pretty much had to read them and give it the good 'ole college try with a general understanding guess (unable to verify in the codes). When I received my diagnostic, I got 0 out of those 6 question correct. That was a killer in itself.
Fast forward to this exam cycle (I found out yesterday that I passed the exam! Yes!). I maintained my study habits and expanded on what I thought I struggled with during the first exam in April. I remember thinking to myself that the topics I struggled with may not be on the next exam cycle, but if they are I WILL NOT LET IT GET ME AGAIN!. After reviewing material, something hit me- my 2 year old threw one of her toys and knocked me right in the head! (Remember, SMILE! LOL!) What I came to realize is this... I need to make sure to get those last 6 questions correct, 100% no doubt, correct. If you have all the referenced code books, those questions come directly from them. It's a look up problem, not solving a problem.
So, at the beginning of the evening section this go around, when we were allowed to start I flipped to the end of the exam and started on the LAST question, not the first. I did the last 6 questions and then started back at the beginning once I answered the code questions. One right after another... Here's the answer, there's the answer, and so on. Very little wasted time. What it also did was 2 things... 1. After getting some of those answered as what I thought (knew) was correct, I found myself being more calm and having more confidence once I started in on the work out, technical, problems. Was a big plus to get that anxiousness out of the way immediately in the evening. And, 2. It allowed me to 'waste' the time on some of the design and detailing problems that I had previously spent too much time on with the whole 'I know how to do this, but I need to find some more information first'. I used all the time again in the evening portion, but when the 10-5 minute mark was called I found myself with 1 unanswered problem left.
After finishing the exam, I knew I had a real shot at passing. Nervous still, but not deflated and defeated as I had felt in April. So, to me, continuing to study and gaining a better understanding with things I struggled with coupled with HOW I took the evening portion of the exam (doing those last 6 questions first) was the biggest influence on my end. Good luck to you on your upcoming attempt. Study from the material you will use during the exam. Make notes from practice exams (knowing the type of questions in them) but don't hand-cuff and crutch on finding things in material you are not that familiar with. Breathe and stay confident and calm!
Good luck and I anticipate hearing from you once you have indeed seen that glorious green PASS!!!!!
