NJ Devilz, maybe you know this, but one thing that I learned on this website is that only one of written memos is graded. The other one is pre-test. In my case with auditing, I could almost definitely tell which one… but it's probably not always the case.
Also, in Becker they told us that it is important how well your thoughts are organized and how well you use terminology. Supposedly, they don't grade your knowledge of specific rules, the only thing is that you can't give illegal advice.
Lastly, let's remember that sims are only 30% of your grade and might contain pre-test (not graded) material in them… some people here were saying that they left most of simulations blank and still passed.
So, I am pretty sure that you have passed, especially with you saying that you were able to do harder M/C questions well.
