VCE calculators

The VTAC ATAR estimator plus the formulas behind VCE Physics, Chemistry and Biology, in tight no-signup tools.

ATAR estimator

Estimate your ATAR from your VCE study scores. Models the top-4 + 10% next-2 aggregate (max 210), VTAC scaling offsets, and ATAR percentile mapping.

Filtered to the VCAA study designs VCE students sit.

Monohybrid and dihybrid Punnett squares, sex-linked (X-linked) inheritance, and Hardy-Weinberg equilibrium for population genetics.

pH and pOH, weak-acid pH, buffer pH (Henderson-Hasselbalch), Kc, Ksp, dilution, titration, mole conversion, Beer-Lambert, and calorimetry.

Projectile motion, centripetal force, gravitation, Kepler, orbital energy, transformer, Faraday, photoelectric effect, relativity, half-life.

The same calculators are organised for HSC and QCE students too, or you can browse the global index.
