Walk into the exam knowing exactly where to find the answer.

“I took a B1 exam prep course from Dennis Cherenkov. Dennis has a concise teaching style informed both from his experience as a contractor and as an inspector. First and foremost was the marking system. It's a very smart system. I used it and added some personal variations to pass the B1, M1, P1, E1, B2 and R3 exams. … His course and advice helped me land a job. I am currently working as a Building Inspector … I highly recommend this course.”

“Dennis brings a lot of wisdom and experience to the classroom but also a touch of humor. Building code can be dry and legalistic so the humor is much appreciated. I've also had the pleasure of working along side him in the field where his mentorship shines too.”

“The marking system is the key to it all. … Being able to recall the area of the book I need to be in and find the answer quickly is what got me through it.”

“The book marking system was perfect. I had five questions that had the exception in it. Thanks again, great class.”

“I just took, and passed the B-1. Thanks for all of the knowledge and studying advice, your system works great!”

“Well, I finally passed. I want to thank you for your help and guidance in maneuvering that book, and understanding more about where things are and why. You're the best!”

“I took the ICC test and passed first try! So thank you for all the lessons and tips from the class.”

“I enjoyed your B1 class immensely. It helped me pass the test first try.”

“Your instruction was incredibly valuable and helped me pass the B1 Residential Building Inspector exam. … Your guidance has already made a big impact on my journey.”

“I really enjoyed your class, you kept me motivated.”
