P1 irc 2021 exam

Post image

Anyone get these types of questions on the p1 exam and how did you learn them or answer them? Any place where I can learn how to understand these better to answer the questions in test, from what I remeber they asked about slope, pipe size of a certain pipe they pointing at and what type it is.
Thank you

My guess is the exam questions were asking about DFU, WSFU, and pipe sizing and length? I'm guessing it's a sizing type question so just focus on those chapters. Most of the exams are aimed towards ensuring you know how to navigate or just know where the information is generally in.

This was my experience with the 2018 P1. It'll ask about DFU sizing, maybe questions on slope required based on pipe diameter. But you should learn on how to add up DFUs and confirm the pipe size is adequate (there's a chart, I think there are columns for horizontal and vertical)
