The biggest thing this exam tests us on is our determination to pass. I am taking FAR on Sept 8th, so I haven't passed or failed yet, but will share with you how I studied using WileyCPA.
I had about 2.5 months, I started at the beginning of July. I did two lessons a day, there are 75 or so lessons so doing 2 a day gets you through all the material in 38 days. When I did a lesson I would first read the entire section of the book that the lesson was over while taking extensive notes. Then I would do he MCQs in study mode, I know in some lessons the MCQs are very discouraging and time consuming. But because I read and took notes I actually knew what I was reading in the question and was much more proficient. If you are getting the right answers it is a lot easier to take 39 question quiz than it is when you don't know what you are doing. After going through the study mode and reading the explanations on what I got wrong, I took the quiz in exam mode, just so it would register that I did it. I did not watch lectures, unless the lesson was very difficult (i.e. bonds). So that's what I did to get though all the material in a little over a month. I studied about 2-4 hours a day depending on how big a lesson was. I did get behind some days but I just kept going and went back to the ones I missed at the end of the week or something like that.
Now I'm in my review stage and I'm spending two hours a day watching lectures. There are 40 or so hours of lecture and when I started review I had about 20 or so days till the exam, so watching two hours a day gets me though all the lectures. After I watch the lectures I take quizzes on the topics I've watched plus the ones I watched the days before, so it is cumulative. When I'm struggling in an area I go back to it.
I haven't taken my exam yet so I do not know if my method will result in a pass or not. I'm like you though in that I have days where I feel really good, then days I get mad at these stupid questions with their stupid little details… But I encourage you to not give up. Even if I decide to leave accounting one day I still want to have passed this exam because it will be a show of my determination and willingness not to give up. You just gotta hang in there, you'll eventually find a study method that works for you. If you are getting MCQs wrong, don't get mad or discouraged, get even! Find out why you're getting them wrong and you won't again!
