The feedback a tutor gives — without the tutor's price

Most VCE Maths and Science marks are lost on how an answer is written, not whether your child understands it: a missing unit, wrong significant figures, a skipped step, an unbalanced equation. ATAR99 marks their written working mark by mark, the way a VCAA examiner would, and shows exactly which mark was missed and why.

A Melbourne VCE tutor

~$70–80/ hour

One hour, one scheduled session, a handful of questions reviewed.

ATAR99 Pro

$49/ month

Unlimited written answers marked, any time of night, right when they're studying.

Not instead of a great tutor — but for the day-to-day “why did I lose that mark?”, it's there whenever they sit down to study, for less than one session a month.

Question

Find the equation of the tangent to y = x·eˣ at the point where x = 0. (3 marks)

A student's working

dy/dx = eˣ + x·eˣ

At x = 0, gradient = 1

So y = x + 1

AI mark: 2/3

  • ✓M1 Differentiates with the product rule: dy/dx = eˣ + x·eˣ
  • ✓M1 Correct gradient at x = 0 (= 1)
  • ✗A1 Correct tangent: y = xThe point of tangency is (0, 0), not (0, 1) — at x = 0, y = 0·e⁰ = 0. So the tangent is y = x, not y = x + 1.

Why method marks matter — straight from VCAA examiner reports

  • Methods: “each line of working needed to demonstrate a clear, logical and explicit progression, leading to the answer”

  • Chemistry: “The most common issue was students not allowing for dilution or reaction stoichiometry in their calculations”

  • Physics: “a complete substitution … must be provided for marks to be awarded”

That's exactly what per-mark marking checks: not just the final line, but whether each step that earns a mark is actually on the page.

Marking schemes are drafted by us and reviewed by humans. The AI can make mistakes — treat the mark as study feedback, not an official VCAA score or an ATAR prediction. Your teacher and the official assessment scheme are the authority.

What you can check for yourself

  • ✓Try it free first. Every account gets trial papers, instant multiple-choice marking, and 5 free AI marks on written answers — no credit card to look around.
  • ✓Monthly, cancel anytime. Access runs to the end of the billing period; no lock-in.
  • ✓Honest about what it is. Papers are past-exam-style (not official VCAA papers), and the AI mark is study feedback — not an official VCAA score or an ATAR prediction. We don't promise a mark or an ATAR.
