^khiila, thank you! I exclusively used Becker as my study material. What I did was go through all the lectures and all the multiple choice questions again. Some people say they will mainly focus on their weaker areas, but personally, I think it is important that you go through EVERYTHING again.
First, it is likely that you may forget a few details you were stronger in if you don't go through it again. Second, the exams can be so different. I can say my second exam definitely focused on different concepts than my first time around. Remember, you need 75 more points, not 2 more points.
Yes, going through everything again can be a pain, but it is so worth it, and you will likely find you will pick up on concepts quicker the second time around (at least I did). I also did all the SIMS for chapters 1 through 7 (I skipped 8-10, mainly due to time constraints and I am already strong in Gov accounting due to my job). The first time around, I skipped the SIMS for the first 7 chapters, and I think that hurt me. SIMS help you see the full picture of accounting concepts, which I think I lacked the first time.
Also, be sure not to panic when you see SIMS and learn how to use the Authoritative Literature. I didn't do that so much the first time. The SIMS literally caused me to fail last time. I also felt I was dealt a better round of SIMS on my second attempt, which I felt also helped. Unfortunately, that comes down to luck of the draw, but looking back, I could have done so much better and passed the first time if I had just not panicked, read the SIMS, and used the Authoritative Literature.
So, in short, put in the work! Don't take shortcuts! And you will get it! A 73 is very close! I've never used NINJA MCQ, but I certainly think they could help (in fact, if I failed FAR again, I would have seriously considered purchasing NINJA. Thankfully, I didn't need to!)
