PassStamp: PE & FE Exam Prep

Studying for the PE or FE while working full time? You don't have 300 spare hours, and you can't afford to walk in unsure. PassStamp is a PE and FE exam prep app — aligned to the published exam blueprint — built for engineers who study in the gaps, and want to know exactly where they stand before exam day. Pay once. No subscription, no monthly fee.

A REAL MEASURE, NOT THE SAME PROBLEMS ON REPEAT
Most prep apps recycle the same handful of questions until you've memorized them, then call it a mock exam. PassStamp keeps two separate question banks. The practice bank is for learning - guided problems with worked solutions and instant feedback. The exam bank is held out: practice exam questions you've never seen, kept strictly separate, so your mock exam is an honest measure of readiness - aligned to the published exam blueprint, not padded with easy points.

FRESH REVIEW, NOT FLASHCARDS TO MEMORIZE
PassStamp builds a spaced-repetition review schedule from the sessions you finish - no decks to set up. When a concept comes due, it comes back as a brand-new problem with fresh numbers, so you re-derive the method instead of memorizing an answer. Get it right and it moves further out; miss it and it returns sooner.

A READINESS SCORE YOU CAN TRUST
Raw accuracy lies. Your PassStamp score is re-weighted by the published exam blueprint, so it estimates how you'd perform on the real test - not how you did on whichever topics happened to come up. After every session you see your score broken down by knowledge area, with the blueprint weight beside your accuracy. Track your accuracy trend over time, see a per-area radar, and a study-gap chart that points to what to study first.

SESSIONS THAT TARGET YOUR WEAK SPOTS
PassStamp tracks every answer and surfaces the areas dragging your score down. On PE exams, your next session automatically weights toward them - so you stop re-studying what you already know.

COUNT DOWN TO EXAM DAY
Set your exam date and PassStamp shows a quiet countdown on your home screen, with optional study reminders at 14, 7, 3, and 1 day out.

EVERY DISCIPLINE, ONE APP
Blueprint-mapped practice exams and question banks across the FE and PE: FE exam prep: FE Civil, FE Mechanical, FE Electrical & Computer, FE Industrial & Systems, FE Chemical, FE Environmental, FE Other Disciplines. PE exam prep: PE Civil as a separate exam for each discipline - Water Resources & Environmental, Geotechnical, Structural, Transportation, and Construction - plus PE Structural, PE Mechanical (Thermal & Fluids and HVAC & Refrigeration), PE Environmental, and PE Chemical. Every question is generated from its governing equation and weighted to the published exam blueprint - so the practice problems are always fresh, never a fixed set you can memorize.
