CWSP Sample Exam 2010B Questions 4-5

I was thinking about going through the CWSP trio and gave the sample test a try. I had no problem getting Questions 1-3, off by .01g which is within the range from what I've read. When it comes to 4 and 5 though I am having difficulty. Did anyone else have trouble with it, or would you mind taking a look at my part - SW2011?

I am getting:

4) 13074.95g vs 13206.40g.

5) 13740.28g vs 14208.00g.

Thanks for the help.

For reference, here is the sample exam. http://files.solidworks.com/services/certification/CSWP-CORE_Sample_Exam2010B.pdf
