AQA GCSE BiologyCell Biology

Explain how water moves from the soil into a root hair cell. (4 marks)

Water moves from the soil into the root hair cell because the soil is more dilute than the inside of the cell. The water moves down the concentration gradient, across the cell membrane and into the cell.

Illustrative sample data

The 3/4 result shown in the marking demo is an example of the format, not a promised outcome.

Practise beyond the mark

Marking is the core, but a good session can continue with Revision Arcade games, progress, and an AI tutor. The demos below are scripted with sample data.

Every game feeds the same topic progress as the rest of the app.

Scripted demo with sample data

Three quick games per topic

Link Up asks you to find four groups of four connected terms. Timeline Twist has you put events in order with the arrow buttons. Fact or Cap deals you statements to call as fact or cap, with an explanation after every answer.

Games feed your real progress

Finishing a game adds XP and mastery to the topic you picked, using the same rules as the rest of the app. Game scores cap mastery at 70 percent, your streak only moves when you finish a full revision session, and nothing here promises a grade.

A tutor that asks first

Omni checks what you already know before explaining, then sets a quick practice question. It is part of the Premium and Pro plans. AI responses can be inaccurate, so always verify against your textbook.

All three demos are scripted with fictional sample data. Nothing is live and no AI runs on this page.

Spend less time choosing what to revise

Use the feedback as a starting point, then keep the rest of your session focused.

Instant AI marking: answer exam-style and real past-paper questions and get marked against mark-scheme criteria in seconds, with feedback on how to win more marks.
Real past papers: papers split into questions with mark schemes, saved so you can stop mid-paper and resume on any device.
Flashcards, quizzes and games: active recall built from your subjects, including Link-Up, Timeline and Fact-or-Cap.
A plan that counts down: sessions planned around your real exam dates, with a live countdown to each paper.
Knowledge organisers: one-page summaries for every topic, matched to your exam board’s specification.
An AI tutor that knows your gaps: ask about the exact topic you keep losing marks on, in English or Welsh.

Questions students ask

Do I need my teacher or school to use it?

No. You can sign up on your own for free, pick your subjects and exam boards, and start revising straight away. If your school later rolls OmniStudy out, your account joins in.

Which subjects and boards are covered?

AQA, OCR, Edexcel and WJEC/CBAC across GCSE and A-Level, with topic lists matched to each board’s specification, including Welsh-medium subjects.

What does marking actually look like?

You type your answer, and in seconds you see your mark, which mark-scheme points you hit, which one you missed, and exactly what to add next time. The demo on this page shows a real example of the format.

How much does it cost?

Free to start with one full subject. Premium is £4.99 a month for up to 5 subjects, and Pro is £9.99 a month for unlimited subjects. That is less than one revision textbook.
