General Mathematics Scaling TCE 2026: Does It Scale Up or Down?

TASC scales every TCE subject before an ATAR is calculated. The TASC scaling report is the authority on what this subject did.

Does TCE General Mathematics scale up or down?

TASC scales every TCE subject before an ATAR is calculated.

TASC does not publish a per-subject raw-to-scaled conversion for this course in a form we can quote exactly, so there is no figure on this page — the direction above is sourced from the TASC scaling report linked below, and should be read as directional rather than numeric.

You can't change the scaling. You can change the raw mark.

Scaling is decided by your cohort, after the exam, and nothing you do moves it. The raw mark is the only part of this you control — and the General Mathematics hub is 20 full-length model exams with mark-by-mark answer guides, revision notes, practice questions and flashcards, built for exactly that.

The hub shows a sample revision note extract, one full exam question with its worked answer and the complete list of every exam and note title — no account needed to look around. Unlocking General Mathematics for life is $20 once, or $50 for any three subjects. See what's included →

What General Mathematics actually asks of you

The external assessment is one 180-minute written examination with an additional 15 minutes of preparation time for notes on the supplied note paper and highlighting only. Sections A, B, C and D are compulsory; Section E offers two whole alternatives and students answer either Part 1 Networks and decision mathematics or Part 2 Trigonometry and Earth geometry. Each attempted section carries 36 marks and assesses one criterion: Section A Criterion 3, B Criterion 5, C Criterion 6, D Criterion 7 and E Criterion 8. A complete original practice paper contains 216 offered marks because both 36-mark Section E alternatives are supplied, while a candidate attempts 180 marks by choosing one. TASC converts each section mark to a criterion rating, so the final award is not reported as a percentage out of 180. Multiple-choice drills on this site are a learning format rather than a reproduction of the written examination.

The 6 areas of study you are examined on

From the General Mathematics Level 3 (MTG315123) course and External Assessment Specifications v1.2.

  • Module 1: Mathematical modelling, problem solving and statistical investigation
    Select mathematical or statistical models, use technology appropriately, interpret results in context and test the reasonableness of conclusions across statistics, sequences, finance and two-dimensional problems.
    In the exam: Formulate and solve unfamiliar problems, relate findings to the real situation, discuss assumptions and limitations, and draw evidence-based conclusions under Criterion 3.
    Where marks go missing: A numerical result is not a complete conclusion. Name the variables and units, check reasonableness and keep association separate from causation.
  • Module 2 Topic 1: Statistical analysis
    Analyse categorical association with percentaged two-way tables and numerical association with scatterplots, least-squares lines, correlation, coefficients of determination and residuals. Smooth and model time series with moving averages, seasonal indices and trend lines.
    In the exam: Construct and interpret statistical displays, fit and assess linear models, distinguish interpolation from extrapolation, calculate seasonal indices, deseasonalise data and reseasonalise trend predictions.
    Where marks go missing: Residual means actual minus predicted. Interpret r and r² using the named variables, and multiply a deseasonalised forecast by its seasonal index to return to actual units.
  • Module 2 Topic 2: Growth and decay in sequences
    Use arithmetic and geometric sequences and series, together with first-order linear recurrence relations, to model discrete linear, exponential and steady-state behaviour.
    In the exam: Generate and graph discrete terms, determine explicit and recursive rules, calculate finite and infinite sums, find thresholds numerically or graphically and analyse long-term recurrence behaviour.
    Where marks go missing: Do not join discrete sequence points as though the domain were continuous. S∞ is an accumulated series total, while d/(1−r) is an equilibrium of a first-order recurrence.
  • Module 3 Topic 1: Investment, loans and annuities
    Model compound interest, inflation, reducing-balance loans, straight-line and reducing-balance depreciation, annuities, sinking funds and perpetuities with formulas, recurrences and calculator finance functions.
    In the exam: Convert rates and periods consistently, compare effective rates, calculate present and future values, repayments and contributions, and justify a financial recommendation from stated assumptions.
    Where marks go missing: Begin versus End changes annuity timing. An accounting book value is not a resale price, and an immediate deposit must be separated from the amount financed.
  • Module 3 Topic 2a: Trigonometry and Earth geometry
    Solve right and non-right triangle problems using trigonometric ratios, sine and cosine rules, area rules and Heron’s rule. Apply bearings, latitude, longitude, great and small circles, spherical cosine, time zones and travel calculations.
    In the exam: Create labelled sketches, select formulas, retain precision, use Earth radius 6371 km, apply signed latitudes and calculate routes, times and distances in multi-stage contexts.
    Where marks go missing: The ambiguous sine-rule case is outside the course. Use a method that determines a unique angle, distinguish small-circle travel from a shortest great-circle route, and separate longitude models from civil time zones.
  • Module 3 Topic 2b: Graphs, networks and decision mathematics
    Represent graphs and digraphs, analyse paths and cycles, find minimum connectors and shortest routes, schedule projects, maximise flows and optimise assignments.
    In the exam: Use adjacency matrices, Euler’s formula, degree conditions, trial-and-error routes, Prim’s algorithm, EST/LST and float, maximum-flow minimum-cut and the Hungarian algorithm.
    Where marks go missing: Shortest paths and travelling-salesman problems use trial and error in this course; minimum spanning trees use inspection or Prim’s algorithm. A feasible flow needs a matching cut to prove maximality.

How scaling works in Tasmania

In Tasmania, TASC rates each Level 3 and Level 4 course against its criteria, from your school's assessment and the external examination, and combines the ratings into an award from Exceptional Achievement down to Preliminary Achievement. Scaling then converts each award of Satisfactory Achievement or better into a course score on a common scale, by comparing every result a student achieved with the results of every other student across all their courses; in 2025 course scores ran from 1.0 to 26.0. Your Tertiary Entrance score combines your best course scores from any two years of senior secondary study to a total of 60 to 75 points — normally five 15-point courses — and the ATAR is your rank on that score. Scaling is recalculated every year from that year's cohort, so a published score range describes one past cohort and is never a guarantee.

What scaling is not

Scaling is not a difficulty rating and it is not a bonus. It compares how the students in one subject performed across every other subject they took, so a subject moves because of its cohort, not because of the paper. The consequence is practical: you cannot scale your way out of a weak result. The only lever you control is the raw mark, and the fastest way to move that is full-length timed practice against the real exam format.

Should I choose General Mathematics because of how it scales?

Scaling adjusts a whole cohort, not one student, so choosing a subject you will struggle in because it scales up is usually a worse trade than doing well in one that scales down. Check the prerequisites for the course you want first, then your interest and workload, and treat scaling as a tie-breaker. Scaling is also recalculated every year, so the figures in any report describe a past cohort rather than the year you are sitting.
