no prior experience
there were alot of questions on ndt (rt,ut,pt,ect.) spend alot of time on this chapter. other than that the general knowledge part was, i think, relitively easy. the questions in the Certification Manual for Welding Inspectors seemed simular and did help me.
HOWEVER the d1.1 and the visual were very difficult for me, only because of the 2 hour time limit to take the test. make your self very familiar with the d1.1 so you can navigate the code book quickly. the practice exam took me 5 hours to complete, but it must be done in 2 hours.
to save time on the practical (part B) use the 6 inch ruler to measure almost everthing (porosity and all discontinuities). i think the only tools i used were the fillet gage and the ruler. we recieved a practice exam for the visual and i did well on it and within the time restraint, but the actual visual test took me the full 2 hours and i rushed to do that. in other words the practice and the actual exam were very different or i should say worded different...
i recomed getting the 2.4 and the 3.0 and study both. they give these book to you at the seminar, but there is so much info in such a short time you wont have enough time to study it all.
hope this helps any other questions let me know
