I probably studied for BEC a total of 80 hours over 10 days. I felt very overwhelmed while studying due to the variety of topics and how detailed the practice MCQs were. Do not get discouraged that you haven't started B5 yet. If you work hard this weekend you should have plenty of time to learn B5, complete the MCQs, complete both practice exams, and review a little.
As many people have said, I also struggled with variance analysis. While this information is important to know for the exam, I would not spend countless hours at this point trying to understand it and memorize the formulas. As you said, there is no way you can know everything thing so just have a solid grasp of most topics and a basic understanding of everything else.
Going in to my exam I also felt like I did not prepare enough and I was going to fail. I had to just clear my head and go in with confidence. My test was about 60% theory/word problems and about 40% math computations. I knew most of the formulas, but in general they still take longer to complete. Many of the theory/word questions were very detailed (especially IT) and confusing. I was pressed for time the entire exam and only left myself 30 minutes to complete the essays. I was not very confident after the exam, but I ended up getting an 85 so it all worked out in the end.
