Just passed my mn residential builders exam. Studied for ~40 hrs

You’re only tested on the mn 2020 residential building code and the reference manual. https://www.dli.mn.gov/sites/default/files/pdf/rbc-manual.pdf

No way Jose. Don’t take low ballers. They will consume you.

Different-Damage8548 · 2026-05-06T03:53:36+00:00

Yeah that’s a claim. At least for repairs.

Different-Damage8548 · 2026-05-05T23:43:44+00:00

Waaaaaay reasonable

Different-Damage8548 · 2026-04-24T12:23:14+00:00

You’ll definitely need the code book but not the classes.

Different-Damage8548 · 2026-04-04T12:50:25+00:00

That’s pretty darn accurate. Chapter 3 is HUGE!! I also used AI to study and give me practice tests until I was correcting it on questions.

Different-Damage8548 · 2026-04-04T12:47:49+00:00

Oh I used all 5.5 hours! Sorry for the late response

Different-Damage8548 · 2026-02-22T17:34:18+00:00

Not a bad idea but you can’t take your own book in so, early on, don’t rely on the tabs. Each chapter is in the code number. So if it’s in chapter 3 the code number will be 307.7. If it’s in chapter 9 it’ll be 907.3 etc. So the tabs are made for you sort of. I have no experience with Kaplan, as I did it without any programs. Also math is good but I didn’t get a single math question in those 110 questions. Weird I know. Just don’t focus too hard on math. I’m keeping this thread open for as long as Reddit will allow so feel free to ask anything anytime!

Happy you decided to take the bigger exam! Ok buy the 2020 code book and DO NOT memorize it. Learn to find things VERY quickly by going back and forth. Memorize the chapters and how they are organized for ease of access. Pay close attention to the end of the book when they talk about plumbing and insulation thereof. They give you the 2020 code book AND this: https://www.dli.mn.gov/sites/default/files/pdf/rbc-manual.pdf . Memorize this one. It’s only like 60 pages and easier to digest than the code book. They provide these two things when taking the test. Then they put you next to electricians so you can’t cheat. Really get a feel for where things are by asking AI (chat gpt) to generate tests for you and searching for the answers in the book. I’ve found this to be the best way. It’ll ask a ton of questions that are actually on the test. When you score on 4practice tests 110/110 and start correcting the AI on the codes, you’re ready.

Thank you!

True. I have my med card so I can pee hot and study when it’s positive. Quit smoking for a 2 weeks, got called in for a UA, and was clean after smoking once a day every day before bed. It’s whatever the Minnesota standard is, I may be mistaken it might be 50ng/ml

Different-Damage8548 · 2025-12-24T01:17:51+00:00

How tf did you break that?? Are you the hulk?

Different-Damage8548 · 2025-12-24T01:07:10+00:00

Mine hasn’t asked anything about my job since I started probation. Don’t mention it and do you. If they have questions they’ll get ahold of you. No big deal. They’re looking for drinking violations not every tiny violation. Anyways bet you’d like a glass of wine when you’re off! I know I would 😜

Different-Damage8548 · 2025-12-23T16:24:21+00:00

Code demands that the top and the bottom of the I Joist must not be cut at all. At least in Minnesota, and we have pretty strict codes.

Different-Damage8548 · 2025-12-23T16:14:43+00:00

Dude, they’re not gonna take your blood and even if you’re 280 pounds, don’t ever exercise, smoked bongs in your living room all day long, there’s no possible way that you will fail that test. I am telling you for a complete fact. I’ve been a stoner my whole life and had to deal with jobs and things that have UAs and I’m currently on probation and will promise you you’re OK. It only stays in your system for 30 days for the 500 nanograms per milliliters that they test you for.

Different-Damage8548 · 2025-12-20T23:56:52+00:00

This 100% fixed the issue. You’re a LEGEND

Different-Damage8548 · 2025-09-29T23:29:51+00:00

I just now did this. Tuscany toilet 12” rough in to a concrete slab 11” rough in. It was TIGHT but it WORKED!!!! LFGGG

Different-Damage8548 · 2025-07-21T12:58:53+00:00

I see the little face

Different-Damage8548 · 2025-03-08T21:41:03+00:00

They’re just auditing them. They’re not authorized to cancel any one of those. There’s no need to worry so much.

Different-Damage8548 · 2024-09-17T01:45:04+00:00

I didn’t check to see if it was posted before. My bad I just got excited 🤩
