Here are some tips although a lot of tips are available. I would say go through all the topics once. New format is not difficult at all. It's just like solving some straight forward equation without an option, just like fill in the blanks. I was also a bit stressed, when I came to know that the format of the exam has changed but I think the changed format questions are simpler than the actual ones. Extra Info about the FE Civil Exam: 1. The exam is straightforward, go to the exam specifications provided by NCEES and follow them exactly. 2. I covered Michael Lindenberg book, 1000 practice problems by Lindenberg and a NCEES practice exam is must. They will deliver you the exam at home as a booklet with solutions. Trust me, Lindenberg book doesn't cover all the material but it will get you till the passing score. The practice test will be same as the actual exam and will also clear many of your doubts. 3. There will be some easy and some difficult questions on the exam, the only thing to keep in mind is that each question is worth just one mark. The key is to keep moving without stressing too much on the question you don't know. You can always guess that. 4. Avoid silly mistakes in rush. (I did one by adding 9+4 = 15, solving whole equation correct and marked the wrong answer) 6/10 times your calculated incorrect answer is there in the options too. 5. Arrive early, I started my test around 7:30 AM instead of the scheduled time 8:00AM. You can avoid few people for 30 mins, some of them bang the keyboard while typing. 6. Know your Calculator (it will save you a lot of time) I have a fx-115ES plus, there is an Alpha option in the red at the top. Let's say, if you want to find hydraulic radius in the Manning's equation when the flow rate is given. You can just enter the equation as it is by putting X instead of the hydraulic radius and press shift plus solve, it will give you the value of X which is your hydraulic radius. Practice this a couple of times and you will be very happy with the outcome. It is very handy in the concrete and steel design questions while finding the area of Steel or the depth of stress block. 7. very useful tip, sometime the solution is in the problem itself. Read the units properly, for example the options are m/sec2. Then you should know that distance part of the question is in numerator and time squared is in denominator.
Good luck
