EnginPrep vs Engineering Formulas

Pass the FE exam with EnginPrep, the FE prep platform built by an engineer who’s been through it. Practice on your phone, review on your laptop, and keep every bit of progress with one account on enginprep.com and this app. Start free, no sign-up required: three new FE problems every day with complete worked solutions, for both Civil and Mechanical. FREE DAILY PROBLEM SET A fresh set of three exam-style problems each day, the same set on the website and in the app. Work them, check your answer, and read the full solution. FULL ACCESS INCLUDES Quick Practice Choose your topics and work through hundreds of problems written to the NCEES exam specification. Every problem has a step-by-step solution, and figures zoom so you can read every dimension. Content Review A lesson for every topic on the Civil and Mechanical FE specs, with practice problems you can regenerate for new numbers until the method sticks. Exam Mode Timed mock exams that mirror the real FE: topic weighting from the NCEES spec, a full-length 110-question exam or a shorter session, breaks, and no feedback until you finish. Then a score breakdown by topic so you know exactly where you stand. Weak Spot Drills The app tracks your accuracy by topic and builds a drill from your lowest-scoring areas. Spend your study time where it counts. Progress Tracking See accuracy by topic, sessions over time, and your daily streak — synced with the website so you can study anywhere. ONE ACCOUNT, EVERYWHERE Your EnginPrep subscription covers enginprep.com and this app. Start a session on your phone during a commute and finish the review on your laptop that night. Built for the FE Civil and FE Mechanical exams. Works on iPhone and iPad, light and dark mode. Questions? Email team@enginpeers.com.

EngiRef is the all-in-one engineering reference app that works 100% offline. Access formulas, material properties, reference tables, and a powerful unit converter - all without internet connection.
