@Aimers I just read your post and it really made me want to respond. 6 months ago I felt exactly like you did. You can go back and read some of my posts. I failed 4 tests (FAR-68, AUD -74, Aud-74, Reg-68) from April through Nov. I literally was at the point of walking away. I missed my wife, I missed doing things on the weekend, and I felt above all, just broken. Im an internal auditor for a fortune 500 company, Im married and my wife is pregnant. So my time is limited.
I can tell you now that if you walk away from this exam, you will regret it for the rest of your life. You have to get back up! You owe it to yourself to give this thing the effort it derserves. I did the same, and I now just passed AUD and REG in back to back windows. There is hope for you. You have to believe in yourself! How are you studying?
What works for me, is I have begun re-reading my Becker book, section by section. Then I stop and do the Ninja Multiple Choice for that section. Its not always in the same order as the book, but you just look at the topics and match it up. Write down every question you get wrong in your own notes. Then keep doing small progress quizzes, doing the stuff you covered in between. Read those notes every chance you get. At the end, I then keep drilling sets of 20 questions on everything. Do the sims! The Ninja sims are the best ones I've done, because they give you an idea of the topics and instant feedback in scoring. You can never predict the sims, but I have a feeling that is what makes or breaks most canidates, so for me, its been benefical to walkthrough as many of them as I can. When I am averaging an 80% on all topics consistently, I know I am ready to sit. Not a moment before.
I hope this inspires you or any others who are lurking feeling the same. I have been in that boat before and I can promise that it will start to click for you. Good Luck
