June marks the early beginning to what we call 'prep season' around here. As part of that beginning, today is the first day that Week 1 of the MeyerFire PE Prep Series begins.
What is the PE Prep Series? The MeyerFire PE Prep Series is a 20-week weekly series of timed 1-hour, 10-question simulated PE Exams. We simulate the types of questions and pace of the exam with instant graded solutions emailed immediately following each exam. The Leaderboard One of the most fun and advantageous parts of being a part of the Prep Series is that you get to see each (1) your progress in getting better at exam-type questions, and (2) see how you compare against others taking the exam. Each Monday (after a week is up), the Leaderboard will be posted here on the Daily page. This year already has nearly twice the participants as last year - already over 1/5th of all of this year's examinees. If you want to be a part of the PE Prep Series, track your progress and see how you stack up, you can learn more information and join on here. Starting tomorrow you'll now see sample PE Exam problems alongside the Daily questions you're used to seeing here. This will be at least the third year I've published daily exam questions during study season, and the response has been bigger and better each year.
How it Works Each weekday I'll post a sample Fire Protection PE Exam question that mimics the style and length of an exam question, and the following day I'll post the solution. As always, feel free to comment or guess your answer after the question is posted. A control area exists within a fully-sprinklered paint manufacturing facility.

A kickoff typically implies something fun, like a football game or a concert event. Most people studying for the PE Exam don't exactly look forward to spending time learning and reading through the summer. I get it. My hope is to make the studying less painful and a little fun. Here's what is coming your way from this site in 2018: DAILY QUESTIONS RETURN A popular resource for examinees and experts alike returns June 1st - our Daily Problem series. This is a separate subscription from the Weekly Blog.

The Weekly Exam Series is your ticket to regular practice that simulates actual exam conditions. It's a series of 20 mini exams that simulate the Fire Protection PE Exam in a weekly, 1-hour session.

For no additional cost you'll be able to take unlimited 1-hour mini exams that pulls from the largest test bank of fire protection questions currently available. This new feature begins in July. See more about the Weekly Exam Series here. It happened again this year. In talking with a colleague about studying for the PE Exam this October this week, he expressed regret about just now getting materials in line to begin to tackle exam prep. I can completely sympathize as beginning the slow climb of the PE mountain can seem daunting, and I felt exactly the same way when I started preparing for the exam.
Perhaps the beginning of the SFPE Online Review Course this past week signals the official start of PE Prep season, or maybe it is because here we jumped the gun a little early this year and have a handful of practice problems already published. But late start? Come on, it's the middle of July! Over half of our surveyed examinees from last year didn't even begin to study until July & August. Does it hurt to get started studying earlier in the year? No, of course not. But in no way does beginning exam prep in July and August doom someone to fail the exam. One of the most common questions that we hear is simply "how much time or effort does it really take to pass the exam?" And the answer is 182 hours. No, no, just kidding. As we detail in the 2017 Prep Guide of course there's not a precise answer as it varies between each person's experience level, test taking ability, and the effort and quality of practice. While the amount of time studying is important, the quality of preparation and intentional practice can be far more important. What we set to create this year was a way to check how your prep effort is comparing, in real time, to others who are taking the test this fall. Passing the exam is not a simple "the top 62% will pass" each year, but in retrospect if someone happens to land somewhere in that top range, it is probably a safe bet he or she will pass the exam. The Weekly Exam Series helps to answer the need for additional practice, simulates the pace of the exam, and finally offers some indication of "am I preparing well enough?". If you are a new user and considering joining, do know that July is a perfect time to get started. We're offering a free, no-strings-attached 2 week trial for new users if you sign up this July. Just select the 2-Week Trial on our Weekly Exams page here. Please do know that it is certainly not too late to get started preparing for the PE Exam. We are thrilled you're here. Welcome to the 2017 PE Prep Season! While that's not actually a real term, we do get excited around here about it. If you're preparing for the Fire Protection PE Exam this fall, you have come to the right spot. If you're hanging around to quiz yourself or are just interested in the content, you are also most certainly welcome!
