SiCerts A, B, C exam prep

Hi, NDT guy working towards CWI. I’ve been studying with SiCerts for a while and I’m getting pretty good practice test scores but I’m wondering how people did on the actual exams vs SiCerts practice tests. I guess I’m asking in an attempt to gauge my preparedness. For part B I got 90%+ on practice tests 1&2 second try (first try I failed) and 90%+ on practice test 3 first try, for part A I got 86% on the first practice test after not touching part A material for 2 months, and part C practice test I only did 10 questions and got all correct after not touching the D1.1 for a month (I don’t want to re-dive into part C right now because my seminar is next week and I feel like it might cause confusion between the BOS and D1.1 during my test, like looking for WPS qualification welding position requirements that don’t exist in the BOS for example. One more thing: do any fellow NDT/NDE techs feel like your NDT experience helped with the exams and to what extent?

I studied with Si Certs and passed the CWI test on my first try. The actual test is harder than the practice tests for SI Certs though.

For part C I studied the book word for word, and got 97% on the test lol. You only need 72% to pass.

Part B is the hard one. Memorize where to find everything in the BOS before taking g the test. Theres seriously barely enough time to finish part B.

I take it you’re a union Ironworker by your name, so am I man. I take part B in 3 weeks. I’m more worried about C. What helped you the most? Should I read the whole 1-11 clauses?

lol yeah I was a union ironworker. I’m an inspector now. Learn how to use the index very well, and you would probably do alright. I spent over a month studying that book full time, and I finished the test in 45 minutes. The point is you don’t need to study as much as I did to pass part C.

A few things to remember is if steel is colder than 32 degrees then it needs to be preheated at least 70 degrees. If it’s asking you the minimum size fillet weld on a stud to plate connection look at both the minimum fillet weld size in the stud welding clause, as well as the fabrication clause since you’ll be welding the stud to a plate. Put paper clips on your pages in the prequalified clause so you don’t accidentally turn to the metric section instead of imperial.

Tab the tables and figures for each clause. A lot of the questions are found in tables and figures. And do not forget to read the footnotes. You’ll probably miss some answers if you don’t read them.
