i have a question about Part B in the CWI exam. I just completed the 10 day course. In the months before while I was waiting to start the course I studied as much material as I could to get prepared. One of the things i did to study for part B was through on online course. In that course they teach that when you are trying to figure out pre qualified procedure root sizes and root angles, if it asks for say root angle at fit up, you take the as specified and add or subtract from the as fit up column and that gives you your answer. In the 10 day course I just completed they told us to take the as specified, add or subtract from the as detailed and then add or subtract that to the as fit up to get your answer. can anyone tell me which is the correct way?
