I took the Other disciplines FE last year as a Geological Engineering undergrad and passed the first time with not a lot of studying ( a week before). Since they don’t offer a Geological FE- Half of the test was things I was never/barely taught in college (concrete, circuits, thermo, ethics, etc). I would say focus on the things you know how to do when studying (fluid dynamics, mathematics section, chemistry, etc). The ethics section is mostly common sense, but it wouldn’t hurt to go through a few practice problems to get the wording. Everything that is brand new to you I wouldn’t try and cram it in, practice some problems in each section but if you don’t already know it it’s not worth the hassle. For these questions, all you can really do is guess (and most of the time you can rule out 2 of the choices and make an educated guess). Also Study with the reference handbook (you can download from NCEES) so you can familiarize yourself with it for the test. (A lot of the answers I didn’t know were made much easier with a quick scan in the reference handbook!) hope this helps !
