ECE GEAS: General Engineering & Applied Sciences

ECE GEAS — General Engineering and Applied Sciences — is the second of four subjects on the Electronics Engineer licensure exam. It's the broadest paper on any PRC engineering board: engineering economy, physics, mechanics, thermodynamics, chemistry, materials science, fluid mechanics, and a dose of computer fundamentals all share one sitting. Reviewers underestimate this paper because no single topic feels deep — and that's exactly why it trips them.

The next ECE board sitting is October 17–18, 2026. The PRC Board of Electronics Engineering writes GEAS to test breadth, not depth. Around 5,000 candidates write the exam each year and roughly 50–55% pass. Weak GEAS scores are the most common cause of bottom-quartile general averages.

What ECE GEAS Covers

The subject pulls from a wide topic mix. The PRC table of specifications under Resolution 2113 s.2025 weights GEAS roughly:

Engineering economy — time value of money, depreciation, alternatives, break-even. Around 15 items.
Physics — mechanics, waves, optics, modern physics. Around 12–15 items.
Engineering mechanics — statics, dynamics, kinematics. Around 10–12 items.
Thermodynamics — first law, second law, basic cycles. Around 8–10 items.
Chemistry and materials — periodic table, bonding, semiconductor materials, polymers. Around 10–12 items.
Fluid mechanics and heat transfer — fluid statics, Bernoulli, basic conduction. Around 8 items.
Strength of materials — stress, strain, beams, columns. Around 5–8 items.
General engineering management — quality, project management, ethics. Around 5–8 items.
Computer fundamentals — number systems, logic gates, basic programming. Around 5 items.

The Recurring Topics in ECE GEAS

The board pulls from a stable bank. The same archetypes show up cycle after cycle.

Engineering Economy

The single biggest block — around 15 items. The high-yield archetypes:

Present worth and future worth comparisons.
Annuity calculations — uniform series, gradient series.
Depreciation — straight line, sum-of-years digits, declining balance, MACRS conceptually.
Rate of return on alternatives.
Break-even point with fixed and variable costs.
Capitalised cost for perpetual maintenance.

Physics

Mechanics dominates with kinematics, Newton's laws, work-energy, momentum. Optics — refraction, lenses, mirrors. Waves — frequency, wavelength, Doppler. Modern physics — photoelectric effect, atomic spectra, basic quantum. Around 12–15 items spread across these.

Engineering Mechanics

Statics — force systems, equilibrium, trusses, friction. Dynamics — projectile motion, circular motion, work-energy. Around 10–12 items. Read the framing — GEAS items are usually shorter than CELE statics items.

Thermodynamics

First law for closed and open systems. Ideal gas relationships. Basic Carnot cycle. Refrigeration COP. Around 8–10 items at the introductory level.

Chemistry and Materials

Periodic trends, bonding types, semiconductor doping (n-type vs p-type), conductors vs insulators. Polymer basics. Around 10–12 items. The semiconductor block connects directly to the third paper (Electronics Engineering).

Where Reviewers Leak Points

Three patterns repeat:

Treating GEAS as easy — the breadth is the difficulty. Don't underprep.
Engineering economy formula confusion — present worth vs annual worth vs future worth. Pick the right form for the framing.
Unit drift — physics items often blend SI with imperial. Read every problem twice for units.

An 8-Week Plan

Weeks 1–2 — Engineering economy. 80 problems.
Week 3 — Physics. 60 problems.
Week 4 — Engineering mechanics. 50 problems.
Week 5 — Thermodynamics. 40 problems.
Week 6 — Chemistry and materials. 50 problems.
Week 7 — Fluid mechanics, strength of materials, computer fundamentals. 60 problems.
Week 8 — Mock papers. Two minimum.

The Computer Fundamentals Block

Around 5 items. Don't skip — they resolve in under a minute each.

Number systems — binary, octal, decimal, hexadecimal conversions.
Logic gates — AND, OR, NOT, NAND, NOR, XOR, XNOR truth tables.
Basic programming concepts — algorithm, data type, control flow.
Memory hierarchy — registers, cache, RAM, storage.

Engineering Management and Ethics

Around 5–8 items. The high-yield topics:

Project management — CPM, PERT basics.
Quality management — TQM, ISO 9000 conceptually.
Engineering ethics — RA 9292 (Electronics Engineering Law) and the Code of Ethics.
Safety — basic OSH framework.

How GEAS Connects to the Other ECE Papers

GEAS feeds the other three papers. The semiconductor materials block feeds Electronics Engineering. Engineering mechanics feeds antenna mechanical design. Engineering economy feeds telecoms project costing on Electronics Systems. Mathematics from paper one feeds the calculus inside physics and mechanics problems.

Drill in parallel. The cross-references reinforce each other.

Where ECE GEAS Differs From Other Engineering Boards

The CELE has a maths-and-surveying paper that's deeper but narrower. The ME has math-and-engineering-sciences that's deeper still. ECE GEAS is the broadest — and that's what makes it tricky. You can't go deep on every topic; you have to know the recognition forms cold and let speed carry you.

The trade-off is favourable. GEAS items resolve faster on average than the other ECE papers. A reviewer who drills GEAS to a strong recognition baseline can finish the paper with time to spare and use the surplus on Electronics Systems or Electronics Engineering.

How Super Tutor Drills ECE GEAS

Our ECE Electronics Engineering track runs subject-tagged practice with GEAS split into the nine sub-domains so you can see exactly which block is dragging your average. Every item carries a worked rationale that walks the formula, the unit conversion, and the common trap. The Focused Yearly tier is ₱1,999/year, around 80% less than equivalent classroom review.

For broader context, see the engineering board review pillar. For the companion ECE paper, the electronics systems strategy guide covers the fourth paper. Civil reviewers can cross-reference the engineering economy block with the CELE math, surveying and transportation guide. STM's grade 12 electronics engineering page and grade 11 mathematics page backfill the foundational topics. The PRC Board of Electronics Engineering publishes the current TOS — confirm before each cycle.

FAQ

How heavy is engineering economy?

Around 15 items — the largest single block. Don't underprep.

Is GEAS easier than the other ECE papers?

Per item, yes. As a whole, no. The breadth makes it deceptively hard.

Should I memorise interest formulas?

Yes. The six standard time-value-of-money formulas. The PRC may or may not supply tables — don't depend on them.

What's the worst trap?

Treating GEAS as a refresher rather than a primary subject. It carries 25% of your general average.
