Where you stand

Conservative 6 · Base 7 · Optimistic 7 · Target 8

From 3 timed papers: 61%, 58% and 63%.

Boundaries: the highest of June 2024, 2025 and 2026, AQA GCSE Chemistry 8462 (Higher tier): 8 needs 137 of 200, 7 needs 120, 6 needs 94.

Topics

47 of 125 points tested

01

Every piece of work lands on a spec point.

So you revise the points you are losing marks on, not the ones you already know.

  1. 1 of 5

    Catalysts, 4.6.1.4.

    One of the 125 points in AQA GCSE Chemistry. Every point starts with nothing on it.

    Never touched

  2. 2 of 5

    You link a note and a deck to it.

    Now there’s something on it. But making notes and cards isn’t the same as getting the marks, so it isn’t tested yet.

    Not tested yet

  3. 3 of 5

    A paper question on it: 1 of 4.

    Log a paper question by question and each mark goes to the points that question tests. Under half the marks means losing marks, and the question goes on your re-attempt list.

    Losing marks

  4. 4 of 5

    Two more papers: 6 of 6, then 5 of 5.

    That’s 12 of 15 across three papers. It still isn’t solid, because the question you got wrong is waiting to come back.

    Getting there

  5. 5 of 5

    You get that question right twice.

    It comes off the list. Most of the marks, nothing outstanding: solid. That’s one point. The app does this for every point on the spec.

    Solid

02

So the gaps are plain to see.

So nothing on the specification is missed by accident.

AQA GCSE Chemistry · 8462 · 11 sections

47 of 125 points tested

  • Nothing on any of its 14 points yet.

When the app suggests a link, you see the suggestion, but the dot doesn’t move until you say yes. A guess never turns a point green.

03

Your papers say where you stand.

So the grade you are heading for comes from your papers, on the board’s own boundaries.

Where am I losing marks in Chemistry?

  • Read Specification coverage
  • Read Grade bands

You’re getting under half the marks on three points:

  • 4.3.2.4Limiting reactants
  • 4.6.2.4The effect of changing conditions on equilibrium
  • 4.6.2.6The effect of temperature changes on equilibrium

4.8 Chemical analysis has nothing on any of its 14 points yet.

Safety

Every message is checked for self-harm, abuse and eating-disorder language before asterisk ai answers. When the check fires, no AI reply is sent and helplines are shown instead: in the UK, Childline (0800 1111) and Samaritans (116 123); other countries’ lines where the app has them. It is verified in English only.

Built on how memory works.

The methods with the strongest research behind them, built into every card, paper and plan.

Spaced repetition
Each flashcard comes back after a longer gap every time you remember it, and its last review lands before your exam, not after it.
Cepeda, Vul, Rohrer, Wixted & Pashler, Psychological Science, 2008
Retrieval practice
Flashcards, timed papers and marked answers make you produce the answer instead of rereading it. A question you got wrong comes back to try again.
Roediger & Karpicke, Psychological Science, 2006
Interleaving
On pro and max, the plan mixes subjects across each day, so one subject does not follow itself where another can go between.
Rohrer & Taylor, Instructional Science, 2007
A model of forgetting
On pro and max, the plan estimates how each topic fades since you last worked on it, using the forgetting curve from FSRS, an open-source scheduler fitted to real review data.
Murre & Dros, PLOS ONE, 2015

07

For parents and teachers.

What they see is the record: hours, papers and grades, never notes or messages.

A weekly email
If your child turns it on, one email goes each Sunday to the address that gave consent for their account: hours by subject, the papers they logged and the grades those papers reached. Never their notes or messages.
Paying
Plans are optional. A 13 to 17 year old can pay with their own card, or send you a link to pay from your own email address, with no account of your own.
Safety
Every message to asterisk ai is checked for self-harm, abuse and eating-disorder language before any reply. When the check fires, no reply is sent and helplines are shown instead. It works on words and is verified in English only.

A class code
Make a class and give students its code. Any adult with a confirmed email address can; there is nothing to apply for.
Set work
Set the class a flashcard deck or a past paper from the index, and see who has done it and who has not, by first name.
The class report
Hours and papers across the class, from what students have logged. No messages, no profiles, nothing a student typed.

Questions from students and parents

Something else: open the app and ask asterisk ai. A guest gets 3 messages without an account.

Honestly: partly, and we would rather tell you where the edges are. There is a filter watching the messages you send to the AI for self-harm, abuse and eating disorders, and when it fires the chat stops, with no AI reply at all, and gives you helplines instead: in the UK, Childline (0800 1111) and Samaritans (116 123); the app shows other countries’ lines where it has them. It works on words, so it will miss things said sideways, and it has only been checked in English: the other languages in its list have not been verified by anyone fluent yet. It is not a substitute for telling someone you trust. Your own notes, cards and tasks are not checked; anything you publish to the Library is, before other students can see it. There is also an age question during onboarding that limits non-study chat for under-13s.
