Wait...are you studying for the FE without getting an engineering degree? Props to you. One thing to keep in mind though is that there is a morning and afternoon session that are both 4 hours iirc. The first session is always a general session which covers the absolute basics of Engineering math, circuits, thermodynamics, statics, Dynamics, chemistry, and physics. It really is very easy if you remember the classes. Some of the circuits problems can be done in your head and the statics problems might have the resultant force being part of a 3-4-5 right triangle (again, it shouldn't take much thought). The purpose of this is to ensure you learned the absolute bare minimum in these classes. One reason the general questions have to be easy is that depending on your course schedule, it might have been two years since you took a course (Ex: you might have taken only one thermo class as an electrical engineer during your sophomore year). The afternoon test is either also general or specialized to a discipline (Ex: chemical engineer) and are much more difficult in comparison. I barely studied for the FE and felt I knocked it out of the park (especially the morning session). I spent months of all my free time studying for the PE and failed the first time...it is difficult. Keep in mind that both of the tests have a lot of breadth, but little depth. Going into an actual Engineering curriculum will teach you a whole lot more. MIT used to (might still) have a circuits Edx class online for free which covers the first out of 3 circuit classes a EE will take...that should help a little with the scale.

Software is weird as the hardware, languages, and frameworks are always changing and the optimal work done on any project seems to be just enough to keep the customers from going to a new product and not necessarily the best or even a good product in many cases. There are cost constraints in Engineering as well (good, fast, & cheap...pick 2), but it still feels pretty different to me than software engineering where something breaks all the time in any non mainstream software I've ever used.
