Selective School Test & OC Test preparation Exam prep that adapts to your child.

More than practice questions. iClass finds the exact gaps, re-plans every week, and tells you whether your child is on track for their goal school. Study Buddy guides them like a private tutor, so they understand, not just find the answer.

Why it's intelligent

It learns your child, then plans around them.

A book of practice papers is the same for every child. iClass changes with yours: it forecasts whether the goal is reachable, finds the exact gaps, re-plans the week around them, and remembers everything along the way.

Goal Feasibility Index

Forecasts whether the goal is reachable

From your child's own answers, it estimates the chance of reaching the target school by exam day, and flags it early when a goal is at risk.

Gap analysis

Finds the exact skill that's costing marks

Every answer maps to a skill, so the gap is named precisely, not "needs more reading".

Long-term memory

Study Buddy remembers your child

What they found hard in March, what they have since fixed, and how they learn best, carried into every session.

What Buddy knows about Mia

  • Goal: Sydney Girls High School, May 2027
  • Fixed in June: fractions in word problems
  • Rushes inference questions when tired
  • Learns best from a worked example first

Other options do one part. iClass does all of it.

Books, question banks, a weekly tutor and AI chat each help with something. None of them knows whether your child is on track, or what to do about it next week.

What's inside

Everything an exam year needs, in one system.

Each part feeds the next. Practice and mock results show where your child is losing marks, the plan moves the right lesson forward, and the weekly report shows you whether it worked.

Personalised learning plan

Built around the target school and the exam date. Two short activities a day, rest days included, re-planned every week.

Targeted lessons

More than 130 guided lessons that teach each exam skill with worked examples, plus the tips and tricks our exam team uses.

Practice that targets gaps

15,000+ exam-style questions. Each one maps to a skill and comes with an instant explanation, so weak areas get named and fixed.

Real mock tests

Full timed papers in the same on-screen format as the Selective and OC tests, so nothing on exam day is new.

Study Buddy

Like a private tutor who knows your child.

A good tutor remembers what your child struggled with last month, notices when they rush, and knows what to teach next. Study Buddy does the same, every day, on every lesson and question.

  • Knows your child

    Their goal school, their pace, and the skills that keep slipping, remembered across months.

  • Guides, never gives the answer

    Hints and explanations that get your child to the answer themselves. Your child does the thinking.

  • Keeps them moving toward the goal

    Points to the next lesson or practice set from the plan, so every session counts.

  • Answers you, in your language

    Ask how the week went or what to do next, and get a reply in the language you prefer.

Study BuddyMia's study buddy

I study with Mia every day, so I can tell you what she has actually done rather than guess. Ask me anything about her.

How did Mia's study go this week?

Mia improved this week, but missing one planned session means there is not yet enough evidence to say the plan is firmly on track.

  • She studied for 105 minutes, and readiness increased from 68% last month to 74%.
  • Reading inference reached 71% (from 58%), Thinking Skills 76%, and Maths 81%. Multi-step patterns and word problems need more practice.
  • Daily habit: 10 minutes in Vocabulary Builder.
  • Next: complete the planned session, including the writing task.

Staying on track

Set the goal once. Know every week if it's on track.

Outcomes are not released until August for Selective and September for OC. So iClass checks progress against the goal every week, while there is still time to change course.

  1. Step 1

    Choose the goal

    The exam and target school. A short diagnostic sets the starting point.

  2. Step 2

    Follow the plan

    Lessons, practice and mock tests in the right order, with Buddy alongside.

  3. Step 3

    The plan adapts

    Gaps found in practice move the right lesson forward the next week.

  4. Step 4

    You get a clear answer

    A weekly report: on track, at risk or not feasible, and what to do next.

See it for yourself

What your child uses every day, and what you read every week.

For your child

Today's plan, ready to start

Two activities a day, rest days included, with Buddy on every screen.

For you

Progress toward the goal, at a glance

Study time, sessions completed, exam-level accuracy and goal status on one screen.

Mock tests

Instant feedback on every question

Every answer comes with an explanation, so your child understands why, not just what.

Five students each make a statement:

  • Alex: “Exactly one of us is lying.”
  • Blake: “Exactly two of us are lying.”
  • Casey: “Exactly three of us are lying.”
  • Drew: “Exactly four of us are lying.”
  • Erin: “All five of us are lying.”

Questions

Frequently Asked Questions

Clear answers for parents choosing a smarter exam-prep path.

What is iClass, in one sentence?

An intelligent learning system for OC, Selective and Scholarship exams: a personalised plan, targeted lessons, practice and mock tests, with Study Buddy guiding your child and a weekly report telling you if they are on track.

How is Study Buddy like a private tutor?

It remembers your child's goal, their work and the skills they find hard, and uses that to explain, give hints and point to what to do next. Unlike a general AI chat, it works from our exam team's lessons and never writes the answer for your child.

How do I know if my child is on track?

Every practice question and mock test updates a skill-by-skill picture of your child. Each week it is compared with the target school and the time left, and you get a clear on-track, at-risk or not-yet-feasible status with the next steps.

Can we try iClass before paying?

Yes. Start a 7-day free trial, or try the free Readiness Check and sample lessons with no sign-up. We collect your payment method for a trial, but you're not charged until the trial ends and you can cancel anytime before then. Member books unlock only after the first successful subscription payment.

How much does it cost?

AU$49 a month, or AU$490 a year. Everything is included. Monthly billing has no lock-in.

How do I prepare for the NSW Selective School Test and OC Test?

Start by finding out where your child actually stands, then work on the weakest skill rather than on more questions in general. iClass builds that into one plan: a short diagnostic gives the first honest reading, guided lessons teach each skill before practice, timed mock exams rehearse the on-screen format, and a weekly report tells you whether the target is still reachable while there is time to act on it. Our full guides cover what each paper tests, how placement is decided, and the key dates for the current cycle.

Which exams does iClass support?

iClass supports the NSW Selective High School Placement Test (Year 7 entry), the NSW Opportunity Class Placement Test (Year 5 entry), the Victorian Selective Entry High Schools exam, and private-school scholarship exams. Each pathway covers the assessed skills your child needs: reading, mathematical reasoning, thinking skills, and writing where the exam includes it.

Do you sell PDF practice books?

Yes. iClass sells downloadable PDF practice books for families who want printable revision, including exam-style tests, full answers, and writing samples for NSW Selective, Opportunity Class, scholarship exams, and NAPLAN. They complement Study Agent's adaptive online plan.

Why does vocabulary matter so much for selective exam success?

Both the NSW OC and Selective Reading papers include a dedicated Word Choice section that directly tests vocabulary — and beyond that, every question in the exam depends on understanding words quickly and precisely. Reading and Writing together are worth 50% of the NSW Selective Test mark, and both hinge on word knowledge — understanding passages, splitting close answer choices, and expressing ideas precisely. The rest of the paper still has to be read carefully: Thinking Skills questions turn on exact wording, and Mathematical Reasoning presents problems as worded scenarios. That's why iClass includes an AI Vocabulary Builder built on expert-curated word lists — 1,200 words for NSW OC and 1,500 for Selective & Scholarship, tiered from Core to Elite — with word quests, rapid reviews and word-root challenges, so your child's word bank grows alongside their study plan.

A plan, a tutor and a clear path to the goal school.

Set the goal today. Your child starts their plan with Study Buddy, and your first report arrives this week.
