ASBOG Practice Exam Strategy 2026: FG and PG Study System

You searched for an ASBOG practice exam — here is what actually exists

Searches like ASBOG practice exam, ASBOG practice test, and FG exam practice questions usually want one of three things: ASBOG's own official sample questions, a free independent question bank organized around the same eight content domains ASBOG publishes, or a way to know which domain to review before test day. This guide covers all three. It does not repeat the full ASBOG FG and PG exam guide (format, fees, state-board eligibility, and a 16-week plan) or the five worked calculation examples already on OpenExamPrep. Instead, it focuses on what ASBOG itself gives you to practice with, how to turn its published task analysis into a domain-by-domain checklist, how ASBOG's own score-report feedback actually works, and specific exam-day and registration facts worth double-checking before you pay or sit down at a Prometric test center.

This article uses ASBOG's candidate handbook (PDF-dated September 23, 2026), its examination schedule, application process, and domain knowledge base pages as primary sources, cross-checked against a state board fee page. OpenExamPrep is an independent study publisher; it is not affiliated with or endorsed by ASBOG.

What ASBOG itself gives you to practice with

ASBOG publishes more free preparation material than most candidates realize, and it is worth separating from paid products before you buy anything.

• Sample questions with an answer key. The current handbook's Appendix 3 gives 40 Fundamentals of Geology sample questions with an answer key; Appendix 4 gives 31 Practice of Geology sample questions with an answer key. ASBOG states this sample set does not make up a complete examination and instead represents the general content areas and formats — treat it as a format preview, not a predictor of your actual form.
• Eight domain knowledge-base PDFs. ASBOG's candidate resources page links a free knowledge-base PDF for each of Domains A through H, plus a compiled all-domains PDF. These list the actual task statements item writers build questions from, which is more specific than any third-party outline.
• A paid FG prep course. ASBOG's candidate resources page calls its FG Prep Course the official course developed by ASBOG. The course site says six licensed geology educators teach the eight FG domains, sells the domains as priced bundles, and removes access six months after registration. It is a paid product rather than a free ASBOG resource, and it only covers FG.
• OpenExamPrep's independent bank. Our free ASBOG practice questions are original items organized around the same eight published domains, with explanations for each answer — not ASBOG questions, and not a copy of the handbook's sample set.

Be cautious of commercial ASBOG exam dumps or sites implying they hold the live item pool. ASBOG's handbook prohibits copying, recording, or transmitting exam questions, so a product claiming to contain real current exam questions is describing a prohibited act, not a legitimate study aid.

Turn the published blueprint into a time budget, not just a topic list

Appendix 2 of the handbook gives the FG and PG blueprint as percentages across eight domains: General and Field Geology; Mineralogy, Petrology, and Geochemistry; Sedimentology, Stratigraphy, and Paleontology; Geomorphology; Structure, Tectonics, and Seismology; Hydrogeology; Engineering Geology; and Economic Geology and Energy Resources. Our ASBOG FG and PG exam guide reprints the full eight-row table; this section is about what to do with the numbers rather than repeating them.

ASBOG's handbook says the other seven domains implicitly include the Domain A knowledge base (general geology and field methods), and Domain A is the only domain weighted the same, 17%, on both FG and PG; the other seven diverge sharply between the two exams. A workable rule is to treat a domain's published percentage as a floor on practice hours, then shift additional hours toward whichever domain your own diagnostic set shows repeated misses in.

For example, with 40 hours left before a PG attempt, a 22% Hydrogeology weight implies roughly 9 hours as a floor, an 18% Engineering Geology weight implies roughly 7 hours, and a 5% Mineralogy weight implies roughly 2 hours, before any adjustment. If your diagnostic set shows you missing Engineering Geology items at twice the rate of Hydrogeology items, move hours from the floor plan into Engineering Geology rather than finishing a fixed study-guide chapter order. The published percentage describes the whole exam form; it does not describe your personal risk.

The domain checklist ASBOG's own knowledge base actually publishes

Each knowledge-base PDF lists specific task statements: the skills item writers build questions around. Turning those into a checklist beats a generic review-mineralogy reminder:

• A — General and Field Geology: Can you position a feature from remote sensing, surveys, or GIS data and build a correct geologic cross-section or map from field observations?
• B — Mineralogy, Petrology, Geochemistry: Can you identify a mineral or rock from its properties and explain its genesis, not just name it?
• C — Sedimentology, Stratigraphy, Paleontology: Can you apply stratigraphic nomenclature, correlate units across a basin, and read a fossil assemblage for age or environment?
• D — Geomorphology: Can you classify a landform and its surficial material, then determine a relative or absolute age relationship for it?
• E — Structure, Tectonics, Seismology: Can you build and interpret a structural cross-section or projection and evaluate an earthquake mechanism?
• F — Hydrogeology: Can you characterize vadose- and saturated-zone hydraulic properties, assess aquifer yield, and trace contaminant fate and transport?
• G — Engineering Geology: Can you characterize a material's engineering properties and turn a site investigation into a design or hazard recommendation?
• H — Economic Geology and Energy Resources: Can you distinguish a resource from a reserve and support an economic evaluation with exploration or geochemical data?

Download the Hydrogeology and Engineering Geology PDFs first if you are sitting PG, since they carry the two largest PG weights. Use our ASBOG cheat sheet for a fast recall pass on the vocabulary each domain assumes, and the ASBOG flashcards to drill the terms you keep missing.

Read your own diagnostic, because ASBOG's score report will not always do it for you

A detail many candidates miss: ASBOG ties its domain-level feedback to failing, not to every result. In the handbook's own description, candidates who fail the examinations receive a plus or minus rating for each content domain in the test blueprint, where a plus means acceptable performance and a minus means substandard performance. The handbook does not describe passing candidates as receiving that same domain breakdown.

That means the only guaranteed, official, per-domain feedback arrives after a failing attempt, not before one. If you want domain-level information while you can still act on it, you have to generate it yourself: tag every practice question you answer by its Appendix 2 domain letter, A through H, and keep a running tally of misses per domain. Our free ASBOG practice questions show each item's domain category after you answer and include a Missed mode for re-drilling wrong answers; if your tool of choice does not show the domain, label it yourself from the task list above. A single missed question tells you little. A domain that is still wrong on a third attempt across three different sessions is a signal worth acting on before you pay for another sitting.

Three official-source conflicts worth verifying before test day

Reviewing ASBOG's own pages side by side turned up conflicts candidates should check directly rather than assume:

1. Allowed items in the testing room. ASBOG's live examination-schedule page says candidates may bring an approved, non-programmable calculator with its cover removed, plus a straightedge, protractor, and engineer's scale. The dated handbook's own room-item list allows only a non-QWERTY calculator without its cover, your admission IDs, a locker key, eyeglasses without their case, and a light sweater or jacket, and separately states the exams are closed-book and bars items such as stereographic nets and tracing paper outright. Confirm current allowed materials with IQT, the scheduling administrator, before you pack anything beyond a calculator.
2. Which states need extra preregistration. ASBOG's live candidate resources page lists an extra application-submission step in the Prometric candidate portal for Georgia, Illinois, Minnesota, and Utah. The handbook, PDF-dated September 23, 2026, describes the same preregistration step for only Georgia, Illinois, and Utah, with no Minnesota. If you are applying through any of these four boards, especially Minnesota, ask the board whether you must complete the portal step before you can expect a scheduling email.
3. Reschedule and cancellation fees. The handbook lists a $50 fee to reschedule or cancel within the allowed window; ASBOG's live registration page lists $35 for the same action. Our ASBOG exam guide notes the same conflict. The short version is to confirm the actual charge in the Prometric scheduling portal before you request a change.

The state board still owns your application, and a seat-fee conflict reaches further than ASBOG's own pages

ASBOG's application page states plainly that ASBOG does not communicate directly with candidates about applications and does not accept application forms or fees from them directly. The process runs: contact the geology licensing board in the state where you want to be licensed, submit your application and transcripts (plus experience documentation for PG) to that board, wait for board approval and its upload to the Prometric registration system, then pay and schedule once Prometric emails you.

The national exam fees are $200 for FG and $250 for PG. The Prometric seat fee on top of that is where sources disagree: ASBOG's own live registration page lists a $78 seat fee per part, for totals of $278 FG and $328 PG, while the dated September 23, 2026 handbook lists $75 per part, for totals of $275 FG and $325 PG. This is not only an ASBOG-internal inconsistency. The Texas Board of Professional Geoscientists fee page lists the FG exam as $200 to ASBOG plus $75 to Prometric, and the PG exam as $250 to ASBOG plus $75 to Prometric, matching the handbook's figure rather than ASBOG's own $78 web page. Texas also layers on its own $25 exam-application administrative fee, separate from both ASBOG amounts. Other boards add their own charges on different scales entirely: Oregon's administrative rule lists separate $125 (FG) and $200 (PG or Practice/Engineering Geologist) state application fees, and Kentucky lists a $225 geologist-in-training application fee. None of those state figures are the ASBOG national exam fee; budget for both, and confirm your own board's current number directly.

Given a dated, versioned handbook against an undated web page, the handbook's figures are the better-evidenced ones, but your Prometric checkout screen is the only number that actually charges your card. Treat that as the final word and keep a copy of the confirmation.

2026–2028 testing windows and the testing vendor

ASBOG's FG and PG exams are computer-based tests delivered at proctored Prometric centers, with registration and scheduling coordinated through IQT, isoqualitytesting.com. Per ASBOG's current examination schedule:

ASBOG labels every session a Thursday and Friday, but September 29, 2027 is a Wednesday and the 2028 fall pair falls on a Friday and a Sunday, so treat both fall entries as provisional until ASBOG or your board confirms them.

The fall 2026 session was scheduled for October 1–2, 2026, so if you are planning now, the next scheduled session is March 18–19, 2027. ASBOG says state board application deadlines typically fall 60 to 90 days before the national date; for March 18, 2027, that is roughly December 18, 2026 to January 17, 2027, and some boards set earlier cutoffs. Contact your board for its exact deadline rather than counting backward from ASBOG's schedule yourself.

A 14-day practice sprint before test day

This is a short, tactical sequence for finishing preparation, not a full multi-month plan; see the ASBOG exam guide for that.

• Days 1–2: Take one untimed diagnostic set from our practice questions, tagging every item by its Appendix 2 domain letter. Work through the handbook's own sample set the same way, Appendix 3 for FG or Appendix 4 for PG.
• Days 3–9: Convert your weighted time budget into daily blocks. Open the matching domain knowledge-base PDF before each block and check off task statements you can actually perform, not just recognize.
• Days 10–11: Run the ASBOG flashcards and cheat sheet against your two weakest domains only.
• Day 12: One full, timed, closed-book simulation at exam pace, about 103 seconds per FG question or about 131 seconds per PG question. Score it, then tag every miss by domain again.
• Day 13: Repair the one or two domains with the most misses using the study guide, rather than a fresh pass through every domain.
• Day 14: Light review only. Confirm your admission letter, photo ID, testing-center location, and the current allowed-items list with IQT. Do not start new material the day before a four-hour exam.

Before you schedule

Read ASBOG's candidate handbook in full at least once, confirm your specific state board's deadlines and forms, and use free ASBOG practice questions, flashcards, the cheat sheet, and the study guide to build and act on your own domain-level feedback before the clock is running. These are independent OpenExamPrep study materials, not ASBOG questions, and are not endorsed by ASBOG.
