I am going over the Sample Math test for the Plumbers and Steamfitters Apprenticeship. My b/f is going to take the real test in about a week. We found this sample test and I thought just to be safe I should go through and do it myself. I got to thinking, although I am generally accurate and skilled in math, it might help if anyone out there would be willing to go through the test as well so I can double check my answers and check my formulas or procedures against someone else's if I get any wrong. I need to make sure I am doing the problems right if I am going to be able to help my b/f with a quick refresher.

I know doing and posting all 50 might be a pain so it would be fine to post answers only. If I run into any discrepancies I will be sure to ask for help/explanations!

Here's the link for the test! Thanx so much to anyone who helps out with this one!

I always thought that the antibiotics didn't work properly and that you also got drunk more easily if you did this but now someone has told me it's a myth (although doctors tell you it's true)

I am a manufacuring engineer (mechanical) in the medical device industry - involved with production line support. I have been in a production line support role for about 10 years and am ready for a change. My strengths are project management, communication/intepersonal skills, and leadeship. I am leaving production line support all together because it is at times, stressful with little recognition and growth opportunities. I am considering project mangement, marketing, or productions supervising/management. What do you suggest?
