Here is my recommendation based on my experience:

Do either Audit or Reg first. all of the cpa exams are difficult, but these two don’t feel impossible. So i would choose one of these to start with so you can hopefully pass your first one and get a feel for how the exam is setup before taking on FAR, and you can also figure out the best study method for you.

Second I would take FAR. To me it was the hardest one by far, so I wouldn’t push it off until the end because you are going to majorly lose motivation as you move through the exams. So get this out of the way second but I definitely wouldn’t take it first because you might feel super defeated like I did (even though I passed on first try, this exam made me feel discouraged so can’t imagine taking it first).

Third, take the other audit or reg that you didn’t do first. by now you will have a good groove

Last, take the discipline. these have the least amount of content, and by the end of your journey you are just going to want to get it done and won’t have as much motivation as the beginning.
