Worked solutions for your assigned technical exams

Already have your technical exam letter?
We provide step-by-step solutions for selected codes. Study the official syllabus first, then use our solutions to compare answers and see how marks are earned.
See exams we support
Only your engineering association can assign or change technical exams. Our materials do not replace official guidance or your association’s syllabus.

What we offer

  • View‑only access in an online scrolling PDF (no downloads or printing)
  • Worked Solutions Packs based on real past exams for each exam code. For every exam we cover, we solve every question (for example, if the original exam said “solve any 5 of 7,” we solve all 7 so you can practice every question type).
  • One‑time purchase, online delivery.

What this is not

  • Not tutoring, a course or live class.
  • We don’t answer technical exam questions or provide follow‑up clarifications on these solutions, so please make sure you’re comfortable learning from written solutions only before you order.
  • No guaranteed pass or specific result.
  • These solution sets are based on real past exams and are not updated every sitting.
Our goal is to give you clear, exam‑style worked solutions you can rely on as a reference, even though we don’t provide 1:1 technical exam support.

How to use the worked solutions

1. Start with the official syllabus and textbooks

Get the syllabus and reading list from your engineering association.
Work through the required topics first so you can attempt past exam questions without guessing.

2. Treat it like a real exam

  1. Order the worked solutions pack for your exam code.
  2. Download the matching past exam(s) from your association or library.
  3. Set a timer and attempt every question on your own before you look at any solution.

This shows you your true baseline and keeps practice honest.

3. Mark your work using our solutions

Use the worked solutions to:

  • See what a full‑credit answer looks like for each question.
  • Check which steps, diagrams, and assumptions the examiner expects to see.
  • Spot where you’d earn part marks and where you’d get zero.
  • Identify topic gaps so you know exactly what to review next.

The goal: you understand how marks are earned, not just whether your final number matches ours.

Exams we currently support

Here are the exam codes where we currently have Worked Solutions Packs available.

These Basic Studies exams cover core math, science, and foundational engineering tools you’ll use in many disciplines. For each code listed below, we provide worked-solution packs based on real past sittings so you can see every step of the solution process, how marks are awarded, and how to structure your own answers under exam conditions.

  • BS-1 Mathematics – Covers linear algebra and advanced calculus, including matrices, eigenvalues/eigenvectors, ordinary differential equations, multivariable and vector calculus (Gauss, Green, and Stokes theorems), optimization, coordinate systems, and power series for analysing complex multidimensional systems.
  • BS-2 Probability and Statistics – Probability concepts, random variables, common discrete and continuous distributions, distributions of functions of random variables, sampling and estimation, hypothesis testing, and simple regression analysis for engineering decisions.
  • BS-3 Computation Methods – Numerical and computational methods for engineering, including data representation, approximation and error, and the use of high-level languages or tools (such as MATLAB, C, or spreadsheets) to solve equations and analyse data.
  • BS-5 Digital Logic Circuits – Boolean algebra, logic gates, combinational and sequential circuits, encoders/decoders, shift registers, arithmetic circuits, finite-state machines, and basics of programmable logic and CAD tools for digital systems.
  • BS-6 Basic Electromagnetics – Electric and magnetic fields, laws and equations (e.g., Gauss, Faraday, Ampere, Kirchhoff), and their applications to capacitors, dielectrics, magnetic devices, and other engineering systems.
  • BS-7 Thermodynamics – Basic thermodynamic concepts, first and second laws, properties of pure substances, closed and open systems, entropy and exergy, and standard gas/vapour power and refrigeration cycles.
  • BS-10 Biology – Cell structure, growth, and metabolism; introductory microbiology; interactions of microorganisms with humans and the environment; and engineered biological systems (bioreactors, bio-instrumentation, treatment systems).
  • BS-11 Geology – Earth structure, plate tectonics, earthquakes, igneous activity, minerals and rocks, weathering and erosion, groundwater occurrence and flow, and basic structural geology (faults, folds, discontinuities) relevant to engineering works.
Complementary Studies exams focus on the “big picture” skills around engineering practice: economics, management, society, and sustainability. For each topic below, you can access worked-solution packs from past exams to see how typical questions are asked and how complete, well-structured answers are written.
  • CS-1 Engineering Economics – Economic principles for engineering decisions: cash-flow analysis, time value of money, nominal vs effective interest, present-worth and annual-worth methods, rate-of-return, lease vs buy, capital budgeting, and basic risk/sensitivity analysis.
  • CS-2 Engineering in Society – Engineering in its social, legal, health, safety, environmental, and organizational contexts, including ethics, equity, and sustainable design in professional practice.

Pricing

$100 + tax per solved exam sitting for each exam code.

Example:If your association assigns Mech A1 and we currently have 2 solved Mech A1 exams, your total for Mech A1 worked solutions would be 2 × $100 = $200 + tax.

If you were preparing for 4 exams with 2 solved sittings each, your total would be 8 × $100 = $800 + tax.
