If you are one month away from taking the exam it would be a good idea to do a strength/weakness analysis of different sections and focus the remaining time and effort accordingly.
One suggestion would be to make sure that you don't miss out on low hanging fruits such as Math, Engineering Economics, Ethics etc followed by some of the more general sections from FE Electrical and Computer Engineering portions such as Properties of Electrical Materials, Engineering Sciences, Circuit Analysis and potentially Linear Systems.
Depending on your major and how long you've been out of school you may find some of the core sections i.e. Power, Electronics, Controls, Digital Systems, Computers, Communication/Signal Processing easy.
Given the time left it would be a good idea to at least know the fundamental concepts of core sections and familiarize yourself with the relevant formulas/theory presented in Reference Handbook.
Finally, the more your practice the better it is.
Good luck!
