A question feels impossible when one small step inside it is not automatic yet. Kite and Koi find that step and make it automatic.

How it works

Three steps to start.

  1. 1Pick a topic

    Or start with the one your last attempts say is weakest. It is waiting on your practice home.

  2. 2Answer a real question

    Say what it is testing, then open the walkthrough with Kite or Koi if you get stuck.

  3. 3Mark your working

    Weak topics come back until they are not weak any more. Try another version of any question.

Find the gap. Learn it. Practise until it sticks.

Every attempt builds a picture of what you know, what is shaky, and what to do next.

Real exam questions, filed by topic.
Pick the topic you're weak on and get a real exam question in seconds, not a hunt through past-paper PDFs. Check your working against the mark scheme when you're ready.
Don't just see the answer. Learn how to get there.
Start with what the question is testing, then work through it one step at a time. Try each step yourself, take a hint when you're stuck, and mark your own working at the end.
One question, many versions.
Questions carry their parameters, so we change the numbers and keep the skill. Try another version until you understand it, not until you have memorised the answer.
Know what to work on next.
Every attempt feeds a picture of what you know and what's shaky. Kite and Koi put the weak topics back in front of you, in the right order, at the right time.
Snap a question.
Point your phone at a question in a book, a worksheet or a past paper. Kite and Koi read it, work out what it is testing, and open the topic it belongs to.
Graphs you can touch.
Move a curve and watch the equation move with it. Some ideas are far quicker to feel than to read about, and graphs are the clearest example.
