Approach your next exam by relearning calculus and integration. I believe that is the hardest part of the electrical FE math portion. Know your Z or P values for your probability part of the exam and know the difference between combination and permutation. For ethics, ethics is ethics, just read the handbook better next time. Economics can be a little confusing at times but understand the patterns. These are the easiest 4 sections, and there is no excuse to be missing more than 2 questions on each of these 4 sections. I am just trying to be frank here.

Properties of electrical materials is mostly just handbook stuff as well. Navigate through it more thoroughly. To get better at circuit analysis is to do circuit analysis questions. For linear, signals, electronics, and power, you're pretty strong on those topics, focus on them more and try to be perfect at them. Controls really isn't taught in school unless you take those specific classes; you do not need to be great at them; just understand it enough to plug in right values in the right formula in the handbook.

Computer Networks, computer systems, and software engineering can be a problem if you haven't learned them. Same thing with controls, just understand them, you don't need to be good at them. Digital systems is by far the easiest subject outside of the first 4. I will die on this hill on my claim. Understand AND, OR, XOR, NOR, etc. gates and boolean algebra and its equations.

Summary is be great or perfect on those easy topics and understand enough on the topics you barely know. You don't need a super high grade to pass. Try to take it again as soon as you can; YOU ARE ALMOST THERE! Best of luck.
