    Hello Samuel,

    Taking screenshots of the practice exam and posting them here is perfectly fine since that is a publicly available resource to candidates. I believe however that I found the item you were referring to. At the end of the scenario in the question it says that "each riser must be no more than 6" high". It is not saying this a code requirement but a parameter for this specific case. While 7" is the maximum allowed by the model code, 4" is the minimum so this 6" requirement would be permissible.

    When taking the exam, make sure to use the information directly stated in a question to answer it. That information may not be exactly to the building code but it would also not ever be in direct violation of it either.

    The max riser height is 7" and the min. riser height is 4" per the IBC. For single family residential you can go up to 8 1/4" max.
