With these two books, you can go through the primary exam questions 10 times and the secondary exam questions 6 times. I took the exam yesterday and expect to pass, so I am listing these for sale. There are some markings as shown in the photos, but they are in pencil, so they can be erased, and I believe they do not interfere with solving the problems. If you are concerned, please purchase a new copy. - Title: 2nd Grade Pipe Construction Management Engineering Examination Past 6 Exams Collection - Edition: 2013 - Edition: 2011 - Question Numbers: 28, 29 - Contents: Past exam questions including published questions Thank you for looking.
