★★★★★

“If you want to pass the Mechanical PE, the Full Access Bundle from Mechanical PE Exam Prep is all you need. Dan provides all of the guidance necessary to tackle this daunting task — from setting aside the proper amount of time and getting in the right mindset to great practice problems and amazing step-by-step solution videos. Not only was Dan super responsive and kind, but he helped me get out of my rut and into some practice problems that were adequately challenging without being overly complex and discouraging. The best part — I passed my exam on the first try!”

“I used the full access bundle to pass the PE exam. Having a study plan all set up and ready to follow was the only thing that kept me on track to pass the first time. Talking with Dan about where I was at really helped give me the confidence to book the test and know I was ready. Just commit, buy the full access, put the time in, and it will all be behind you.”

Frequently Asked Questions

Is all the content available immediately?

Yes. All content is available to you immediately upon enrollment. No drip schedule, no waiting.

Are the practice problems similar to real exam problems?

Yes. Most problems are written to be as hard as exam problems or slightly harder. Every problem has at least one key insight embedded within it — and very often two or three.

Are the solutions based on the CBT format?

All 5 practice modules are solved using the NCEES Mechanical Reference Handbook PDF. The companion practice problems book calls out specific search terms to help you find what you need fast.

I’ve been out of school for a long time. Is this right for me?

Yes. By covering the Fundamentals first, you get the background and context you may have forgotten before working practice problems. It may take a bit more time, but the program is designed to work for everyone.

Are the PDFs downloadable?

Yes. For each of the 5 core chapters and the 2 full practice exams, you get all 5 PDFs: Problem Set, Answer Key, Complete Solutions, Key Formulas, and Key Search Terms — all downloadable from the learning platform.

I’ve already purchased a course included in the bundle — can I upgrade?

Yes. Email Dan and he’ll provide a link with a credit for any course you’ve already purchased.
