Sorry to hear that… I think when it comes to FAR, the focus is not the amount of problems you work, but how well you understand the materials. I took BEC/FAR back to back this month and had zero time to work on any FAR MCQ/SIM and was able to pushed for a passing score and here's how I did it. I have Wiley CPAexcel and they offer bite-size video classes on their smartphone app. I only had 2.5 weeks to study for FAR so I spent 5-6 hours a day (2 hours in the morning, 3-4 hours before I sleep during work days) listened through their videos. I did my best to follow the video and wrote down key points for each to help myself understand the concept and for easier recap later on. I also wrote down all key JE's in bonds, revenue recogznition, lease, pension, income taxes, equity transactions in a separate note. For all videos that went through calculation examples, I played the video slow and nice twice to make sure I understand ever step through the calculations and JE, took good notes on the vague parts. By the end of all video lectures, I accumulated two fully loaded notepads and have 4 days left until exam day. For the first two days, I went through all my notes twice and went back to videos on the topics I had forgotten or almost forgetting to make sure I reinforce my knowledge on those parts. On 3rd day, I went to AICPA's website and did all the exam tutorial sample questions twice to get used to the SIM format. And, this is important, I went back to the calculations in the video lecture for bonds, equity, lease, pension, income taxes and re-perform all the video example calculations by myself, twice. The day before the exam, again, very important, I went through my notes on government and NFP twice, other notes once, and video example calculations once.
I should also mention that I took the two days before exam day off to cram through FAR final review which allowed me to go through some intense self-review twice.
This is what I had to do with 2.5 weeks left to study for FAR and passed with a 76. I think you have more time to digest the information better, you'll end up with a higher score.
Good luck and hang in there. You can do it.
