BEC AICPA Released Questions

Regarding BEC studying, the exam day is coming even hurricane Sandy disturbed me of studying.
So I'm trying to do my best whenever and wherever available, whatever happening.

Below is my score of AICPA Released Questions for the past 5 years.

2012 27/40 67.5%
2011 25/40 62.5%
2010 30/42 71.4%
2009 35/50 70.0%
2008 39/50 78.0%

These are only Multiple Questions.
I started from 2012 to 2008.
You know that as I proceed these quizzes, I get better and better.
In 2008, I got a passed rate in the end.

Now I'm reviewing Abitus MC quizzes which I've made mistakes.
Although I did lots of quizzes already, I make the same mistakes with those quizzes.
If I can complete those knowledge with this review, I believe I can get over this BEC shit!!

...well, I have only 3 weeks left and unfortunately I've already known that I have to work for the 2 previous weekends.
I don't how much time I can spend on my studying, I just dedicate to study for my objects.

I can do it if I long to.
