ECE Reviewer has been rebuilt from the ground up. AN ENTIRELY NEW QUESTION BANK 1,000 questions replacing the old 850 — and every one of them now has a worked solution showing the formula, the substitution, and the error the wrong choices are built from. The old version had answer keys and nothing else. WEIGHTED TO THE BOARD The old bank was roughly half circuits-and-devices by accident. The new one is built to the board's own weighting: Mathematics 200, Electronics Engineering 300, GEAS 200, Electronics Systems and Technologies 300. Thirty-two topics, including Laplace and Fourier, engineering economics, RA 9292, fiber optics and cellular networks. TIMED MOCK EXAMS Full-length mocks at the real session lengths — four hours for Mathematics and GEAS, five for Electronics Engineering and EST — plus fifty-item drills. Results rank your five weakest topics so you know what to open next. WEIGHTED RATING ESTIMATE Your accuracy weighted 20/30/20/30, the same way the board computes it. 194 FLASHCARDS Formulas, constants and the pairs everyone mixes up — β and α, 10 log and 20 log, rms and peak — with spaced repetition. EXAM COUNTDOWN Set your own exam date and watch it come. REBUILT APP New design, dark mode, and rewritten from the ground up for modern iPhone and iPad. The old build could not be updated at all. STILL ONE PURCHASE No subscription has been added and none is planned. If you already own this app, the update is free. Thank you to everyone who has used this since 2015. Good luck on the boards.
ECE Reviewer PH is a practice reviewer for the Electronics Engineers Licensure Examination given by the Professional Regulatory Board of Electronics Engineering. One thousand questions, every single one with a worked solution. Everything runs offline. WEIGHTED THE WAY THE BOARD IS Most reviewers give you whatever questions they happen to have. This one is built to the board's own weighting, so the time you spend matches the marks you earn: • Mathematics — 200 questions (20%) • Electronics Engineering — 300 questions (30%) • General Engineering and Applied Sciences — 200 questions (20%) • Electronics Systems and Technologies — 300 questions (30%) EVERY QUESTION IS WORKED, NOT JUST KEYED An answer key tells you that you got number 14 wrong. It does not tell you why. Every question here ends with the formula used, the substitution, and the specific mistake one of the wrong choices was built from — forgetting the 2π in reactance, using β where (β+1) belongs, 10 log instead of 20 log, rms read as peak. Those are the errors that cost real examinees real marks. THIRTY-TWO TOPICS Calculus, differential equations, Laplace and Fourier transforms, complex numbers, probability. Circuits and network theorems, semiconductor devices, BJT and FET amplifiers, op-amps, power supplies, digital logic, microprocessors, instrumentation. Physics, chemistry, thermodynamics, strength of materials, engineering economics, management, laws and ethics under RA 9292. Communication fundamentals and dB, AM and FM, data communications, transmission lines, antennas and propagation, microwave, radar and satellite, fiber optics, broadcasting, networking and cellular. TIMED MOCK EXAMS AT REAL SESSION LENGTHS Mathematics and GEAS run four hours. Electronics Engineering and EST run five. That is the actual board program, and that is how the mocks are timed. Each one samples across its topics in proportion, so a Mathematics mock will not hand you forty integrals by accident. Shorter fifty-item drills are there for when you do not have five hours. WEIGHTED RATING ESTIMATE The home screen shows your accuracy weighted 20/30/20/30, the same arithmetic the board uses. A flat percentage across all four subjects would flatter you; this will not. Passing is a weighted 70 with no subject below 50. AFTER EVERY MOCK, WHAT TO DRILL NEXT Results open with your five weakest topics, ranked. That is the entire point of sitting a mock — not the score, but knowing where to go next. ALSO INSIDE • 194 flashcards with spaced repetition that resurface just before you forget • Exam countdown you set to your own date • Daily 10 for when you only have a few minutes • Progress tracked per subject and per topic • Bookmarks, and an automatic list of every question you got wrong • Light and dark mode • Answer choices shuffle every time, so you learn the physics, not the letter TEXT ONLY, ON PURPOSE There are no circuit diagrams to pinch and squint at on a phone screen. Every problem states its topology in words — "a series RLC circuit with R = 50 Ω, L = 10 mH and C = 1 μF" — which is also how you will have to parse it under exam pressure. ONE PURCHASE No subscription. No weekly plan. No credits. No paywall halfway through GEAS. Buy it once and everything is yours, including future content updates. WORKS WITHOUT INTERNET The whole reviewer sits on your device. Review on the jeepney, during a brownout, at a review center with no signal. No account, nothing to sync. ABOUT THE QUESTIONS Every question is written originally against the published coverage of this exam. They are not reproductions of past board papers, which PRC does not release. ECE Reviewer PH is an independent study aid.
