Answers come back marked like this: the marker quotes your sentences, shows what each one earned, and starts you on the fix worth the most.

Name memory cells, then link them to the faster antibody response on re-exposure.
Most marks are lost when an answer names the right structure but never says what it does.
Explain how vaccination leads to long-term immunity.
Vaccines contain a weakened pathogen (note 1: earned), so the body produces antibodies against it (note 2: earned). If you're infected later, the antibodies fight the pathogen off faster (note 3: partly earned).
Nothing is underlined for these: the answer never says it.
A worked example, not live marking. AI marks are practice estimates, not official examiner results.

Practise questions for your syllabus, then use the explanation to understand the reasoning behind each answer.
At what times does the particle change direction?
1 s and 3 s — where velocity changes sign.
Get feedback on your writing, with strengths, areas to improve and a rewritten passage to compare against your draft.
Draft: “Repeating ‘never’ makes the warning effective.”Stronger rewrite: “Repeating ‘never’ denies the reader any reassurance.”
Turn notes into a deck and practise recalling the answer before you flip the card.
Front: What is homeostasis?Back: Keeping a stable internal environment while conditions outside the body change.
Work through the question in front of you with a hint or a worked example from Avi.
You: “How do I know when a particle changes direction?”Avi: “Check just before and after each time velocity is zero. Does its sign change?”

Four sample questions. Choose an answer, then read the explanation. Nothing to set up, and no account needed.
Which cells are responsible for the faster antibody response when a vaccinated person meets the same pathogen?
Memory B cells persist after the first exposure. On re-exposure they rapidly proliferate and differentiate into plasma cells, so antibodies appear sooner and in greater amounts. Plasma cells themselves are short-lived.
Which functional group makes ethanol (CH₃CH₂OH) an alcohol?
Alcohols carry a hydroxyl group bonded to a saturated carbon. In ethanol it sits on the end carbon, which is bonded to only one other carbon — so ethanol is a primary alcohol.
What is the derivative of f(x) = 3x² − 5x + 2?
Differentiate term by term: 3x² becomes 6x, −5x becomes −5, and the constant 2 differentiates to 0. So f′(x) = 6x − 5.
A 2.0 kg trolley accelerates at 3.0 m s⁻². What is the net force acting on it?
Newton’s second law: F = ma = 2.0 kg × 3.0 m s⁻² = 6.0 N, in the direction of the acceleration. Dividing instead of multiplying gives the 0.67 N and 1.5 N traps.
Now do it with your own course, and get your written answers marked criterion by criterion.
Type a topic or paste your own material. Students join on their phones with a PIN, and you see which distractor pulled the class while it's happening.
Every plan marks your written answers. Paid plans add room for the weeks you need it most.

An AI study tool for Australian Year 11 and 12 students: exam-style practice, answer feedback, flashcards and other study tools, all scoped to your course.
WACE, HSC, VCE, QCE and SACE courses across 136 subjects. Choose your exam system, year and subject in the builder. Unit-level coverage varies by course.
Yes. Try a quiz without an account, then sign up for a monthly free allowance. Paid plans add higher allowances; see pricing for current inclusions.
Use it as practice feedback: a suggested mark, the criteria you addressed and ways to improve. AI can make mistakes. These are not official examiner marks; check uncertain feedback against your course materials or your teacher’s guidance.
No. They are worked examples of the practice loop. Open the quiz builder to answer your own questions and receive AI feedback.
