Issue with the CSWP practice test; wondering if I'm ready?

I've been reading up and practicing using some features that I rarely use in order to prepare for the CSWP. I have been using SW for nearly 6 years. My field involves modeling and drawing mostly round parts. I would guess that 90% of the parts I model are round and most have threads, so the part on this practice test put me out of my element. I use lots of revolves and cut-sweeps with an occasional simple cut-extrude. Some parts have required some fairly complicated lofts, but those are few and far between.

I've completed the practice test 4 times, I think. Two of those times have been in the last 2 days as I am preparing to take the CSWP. This is the one I'm working from - http://files.solidworks.com/pdf/CSWP-CORE_Sample_Exam.pdf

My first issue is that I can barely scrape by to complete this in the 30 minutes that it recommends. On my last attempt, I finished just seconds short of 30 minutes. I make use of mouse gestures, keyboard shortcuts, and the shortcut bar. Should I be finishing this much faster that?

My second issue is that even though I completed it, my answers for questions 4 and 5 are not close enough for me to trust my answers or my model accuracy. I've looked over it multiple times and checked all the variables for accuracy, but I can't find anything wrong with it. I've attached it and would appreciate any input.
