★ DP · HL / SL

Learn it properly.
Then practise like it's the real paper.

Bite-sized lessons you can finish between classes, real past papers with the markschemes attached, an EE/TOK evaluator that remembers every draft you've written, and a tutor that pushes your reasoning toward the command term instead of writing your answer.

HL / SL No card to start. At a Koncepts school? It's already unlocked, just use your class code.
Biology HL · Paper 2 · May session ★ Markscheme attached
Q12 marks
Outline

Outline the role of ATP in active transport.

1 mark, energy released from hydrolysis · 1 mark, moves against the gradient
Q24 marks
Explain

Explain how the sodium–potassium pump maintains resting potential.

Marks for mechanism, the 3:2 ratio, and the resulting charge difference
Q35 marks
Evaluate

Evaluate the evidence for the chemiosmotic theory.

Evidence both ways, and a stated judgement, or the last marks don't pay
Q48 marks
Discuss

Discuss the limitations of the fluid mosaic model.

The marks are for limitations argued both ways, not just listed

ChatGPT will happily write your answer. It has no idea how Paper 2 is marked.

DP marks live in specifics, the command term, the markscheme line, the band. A generic AI gives you fluent prose that scores a 4. Koncepts reads the same markscheme your examiner does, and it makes you write the answer.

01Lessons, not a 40-page PDF

The syllabus, broken into things you can finish.

Every DP topic is a path of card lessons you get through in minutes, each one with a voiceover, so you can clear a subtopic on the bus. Tap to reveal, answer to move on, and find out you've misunderstood something now instead of in the mock.

Card lessons in syllabus orderAudio on lessons, more shipping weekly30,000+ interactives and simulators3D models you rotate and pull apartThe full Library behind every subtopic
Chemistry HL · Rate of reaction Card 4 of 9

Why heating speeds it up more than you'd expect.

AMore collisions per second, as you'd guess
BMore collisions with enough energy to react
CThe activation energy drops
Nine cards, not a chapter. Audio on every one, so the bus counts as revision.
02Real papers and markscheme logic

Practice that speaks the examiner's language.

Authentic DP past papers question by question, marks, command terms and markschemes attached, HL and SL kept distinct.

Authentic past papers, HL/SLMarks + command terms on every questionMarkschemes you learn to read80,000+ exam-style questions
Paper 2 · Q3 · Evaluate 5 marks

Evaluate the evidence for the chemiosmotic theory.

1Evidence for, a proton gradient is measurable across the membrane
1Evidence for, ATP synthase activity stops without the gradient
1Evidence against, uncoupling experiments complicate the picture
2A judgement, supported, not stated
"Evaluate" only pays in full if you land a judgement. The markscheme says so, now you can read it.
03A tutor that pushes reasoning

Guided to the command term, not handed the answer.

Voice and a live whiteboard, but its job is the next question, not the final answer. The same tutor can pressure-test an EE research question.

Asks the next question firstLive voice + whiteboardFluent in command terms and HL/SL
Class Tutor · Chemistry HL ★ Live
1What does the rate constant actually depend on?
2So what happens to k when you raise the temperature?
3Now say that as "explain", what earns the second mark?
It stops asking when your reasoning holds, not when it has finished talking.
04The Adaptive Loop, on your side

Grading that doesn't stop at a band.

Koncepts pinpoints the exact sub-skill you missed against the markscheme and sends a follow-up built for it, receipt included.

Questions

The honest answers

What's actually free?

The first two subtopics of every subject, full lessons, notes, cheatsheets and quizzes, plus 5 AI messages a session and 3 duels a day. It never expires and you can replay it forever. A real sample, not a trial that dies in 7 days.

Does Pro have any limits?

No. Every lesson, the full Library, unlimited AI, unlimited duels. No hidden feature gates.

Will the AI just do my homework?

No, and that's the point. Help mode guides you step by step and won't skip ahead of your understanding. Analyse mode marks finished work like an examiner. You do the work, Koncepts makes sure it's right.

Is the EE/TOK Evaluator allowed under IB rules?

It gives feedback on your own drafts, like a supervisor or a peer reviewer would, and keeps every version so your work's evolution is visible rather than hidden. It never writes your essay. Follow your school's academic integrity policy on AI, and acknowledge AI assistance where your school requires it.

Which subjects are covered?

[N_SUBJECTS] DP subjects, HL and SL, with more shipping continuously. The full syllabus path for every subject is visible before you pay, so you can see exactly what you're buying.

I bought Pro on my phone, does it work on the web?

Yes. Web, Android and iOS, one account, every device.

Can my parents pay?

Yes. Share the checkout link, or subscribe on the web with their card. The subscription attaches to your student account either way.

Can I cancel anytime?

Yes, in one tap, and you keep Pro to the end of what you've paid for. No lock-in, no call to cancel.

Two years.
One grade
that matters.

Start free today. Go Pro when you hit your first wall, and never hit another one.
