The subject areas the exam covers, and how to weight your study

The FS spans mathematics, measurement theory, boundary principles, geodesy and geospatial topics. How to read the specification and allocate study time.

The Fundamentals of Surveying exam covers a wide range of subject matter, and the breadth is the difficulty. Very few questions are hard in isolation; what makes the exam demanding is that the material spans mathematics, measurement science, boundary principles, geodesy, mapping and professional topics, and you cannot predict which will come next.

Before anything else, obtain the current exam specification from the exam provider. It is published, it lists the content areas the exam draws from, and it is the only authoritative statement of scope. This article describes the families of topics qualitatively and suggests how to weight your effort; it is not a substitute for that document, and the specification is revised periodically.

The families of topics

Read the specification's own list rather than this one. Broadly, the material clusters into the following areas.

  • Mathematics: algebra, plane and spherical trigonometry, coordinate geometry, basic calculus and vector reasoning, applied to surveying situations rather than posed abstractly.
  • Basic sciences: the physical principles behind measurement, including optics, wave propagation, refraction and the behavior of instruments.
  • Measurement theory and error analysis: systematic versus random error, propagation of error, weighting, statistical description of observations, and adjustment methods including least squares in concept.
  • Field data acquisition and reduction: instrumentation, procedures, corrections applied to raw observations, levelling, traversing, and the reduction of raw field data to usable coordinates.
  • Plane survey computations: traverses, closure and adjustment, areas, curves both horizontal and vertical, intersections, and coordinate geometry problems generally.
  • Geodesy and geodetic computation: datums, reference frames, ellipsoid and geoid, map projections, state plane and other grid coordinate systems, scale factors and the grid-to-ground relationship.
  • Boundary principles: the nature of evidence, the hierarchy of calls, description types, the public land survey system, riparian concepts, and the general legal framework in which boundaries are determined.
  • Photogrammetry and remote sensing: image geometry, scale, stereo concepts, lidar fundamentals and where each method is applicable.
  • Geographic information systems and spatial data: data models, accuracy and metadata concepts, and how survey data feeds into and out of a GIS.
  • Professional topics: ethics, professional responsibility, business and project practice, and written communication in a professional setting.

About proportions

Candidates always want to know how the questions are distributed, and the honest answer is that the specification is where that information comes from, in whatever form the provider currently publishes it. Any table you find elsewhere may be describing a superseded version.

What follows is not published data. It is a planning heuristic — one reasonable way for a candidate to allocate study time, offered as an approximate personal budget rather than as a statement about the exam's composition.

A candidate's own planning estimate for allocating study effort. Approximate, and not a published distribution.
AreaRough share of study timeWhy
Mathematics and plane computationsAbout one thirdUnderpins many other areas; fluency here speeds up everything else
Measurement theory, errors and adjustmentAbout one sixthConceptually distinct, commonly under-prepared, and rewards a small focused effort
Geodesy, datums and coordinate systemsAbout one sixthFrequently the weakest area for candidates from a field background
Boundary principles and the public land systemAbout one sixthRewards memory more than computation; efficient to study in blocks
Photogrammetry, remote sensing and GISAbout one eighthBroad but shallow; a limited investment covers the common ground
Professional topics and communicationSmall remainderMostly reasoning from principles rather than recall; low cost to prepare

Adjust those shares to your own diagnosis. A candidate coming straight out of a geomatics degree may need almost none of the mathematics allocation and much more on boundary and professional topics. A party chief with fifteen years of field experience will usually find the opposite.

Diagnose before you allocate

The most common preparation error is deciding how to distribute study time by intuition. Intuition systematically over-weights the topics you enjoy, which are almost always the topics you are already good at.

  1. Work a mixed set of practice problems, untimed and without notes, across every area in the specification.
  2. Record for each problem whether you got it right, and if not, whether the cause was a knowledge gap, a computation slip, a misread question, or simply being too slow.
  3. Group the failures by cause, not just by topic. A pattern of computation slips across every topic is a different problem from a knowledge gap in geodesy, and it has a different remedy.
  4. Rank the topics by the product of how weak you are and how much of the exam the specification indicates they cover. Weak areas that carry little weight are not where your time goes.
  5. Re-diagnose after about half your study period, because the ranking will have changed and continuing to work your original weak list is a common waste of the second half.

The areas candidates most often neglect

  • Error theory and adjustment, because it feels academic. It is very well suited to short conceptual questions, which makes it disproportionately worth preparing.
  • Geodesy and map projections, because field practice hides the underlying theory behind software that applies it automatically.
  • Photogrammetry and remote sensing, because many candidates have never used them, and a couple of hours on image scale, ground sample distance and lidar basics covers most of what appears.
  • GIS concepts, for the same reason, and with the same efficient return on a small investment.
  • Professional and ethical topics, which candidates assume can be reasoned out on the day. Mostly they can, but not when you are tired and behind on time.
  • The public land survey system, for candidates in states where it does not apply and who therefore have never encountered sections, townships or the rules for subdividing them.

The recurring theme is that the neglected areas are the cheap ones. Hard computational topics reward long study with modest gains; unfamiliar conceptual topics reward short study with large ones. Early in a study plan, spend your time where the return is highest.

Questions

Where can I find the exact distribution of questions by topic?

In the current exam specification published by the exam provider, in whatever form they currently express it. Distributions quoted on forums and in study guides may describe superseded versions of the exam, so go to the source.

Do I need to know the public land survey system if my state is not part of it?

Yes. The exam is national, and the public land system's principles are part of the fundamentals of the profession regardless of where you happen to practise. For candidates in eastern states this is often an entirely new topic and should be scheduled accordingly.

How much calculus is involved?

Enough to handle basic differentiation and integration in applied settings, such as reasoning about rates of change on a vertical curve or about areas. It is not a calculus exam, and heavy analytical technique is not the point. Fluency with trigonometry matters far more.

Are there questions with no calculation at all?

Yes, a considerable number: definitions, principles, appropriate methods, professional judgment. They take a fraction of the time of a computational question, which is exactly why they deserve a proportionate share of your preparation.
