Although I'm nowhere close to perfect in creating this prep material, I have thoroughly enjoyed constructing this year's set of daily practice problems and I sincerely hope they have been beneficial and helpful to you.

After the exam I'll send a brief survey to gather constructive feedback so I can improve our tools again for next year. Thank you to those who have already provided feedback about the prep guide and the website, it is greatly appreciated!

If you haven't already, consider subscribing to the weekly fire protection blog which covers takeaways on a range of fire protection subjects. 

Thanks and all the best to those taking the exam tomorrow!

I typically see Cooper B-line fig.828 used, the universal seismic clamp on the beam flange. Do they have to be used with a retaining strap on the beam? Manufacturer's instructions is silent in this regard.

When reading NFPA 13 Handbook, 8.16.1.1. The figure shows several layout of valves installation. My question is what is the order to install the valves. Wet system figure shows control valve, then check valve; however the dry pipe system shows check valve first then control valve. So what is the right order to install valves? Or it doesn't matter as long as you have control and check valve?
