What stayed
A concept you once missed counts as held only when you get it right again on a different question, at least a week later.
Skill improvement, through practice
Practise a skill until you can use it.
Practicks is where you improve a skill by practising it. Answer focused questions, learn from every answer, and see — from your own practice — what has stayed, what you can apply on your own, and what you can use somewhere new.
Free to start: unlimited practice, with no time limit, in the first 2 skills you start. No card required.
Practise on the go with the mobile app.
Turning mistakes into understanding
14 concepts you once missed are still right a week later.
Each dot is a concept that once tripped you up. Right again later, on a question that was no easier, is how you know it stuck.

What practice shows you
Not just what you know. What you can use.
Every answer adds to three plain readings of a skill — for you, and for the trainer who runs your cohort.
Applied on your own
Of what you got right again, how much you showed on a question that asks for more than recall — without opening a nudge.
Used somewhere new
Of what you got right again, how much you showed in a realistic work situation, or when it was asked a different way.
Shown side by side, never combined into one score, and never a judgement of anyone’s job readiness. Applying and new situations are added skill by skill as each skill's questions are classified — every skill shows what stayed today. See coverage
Inside Practicks
Every screen answers one question: can you use it?
The same evidence runs through the whole product — from a learner’s home screen to a trainer’s cohort report — so what you see in one place never contradicts another.

For learners
Today, at a glance.
- Outcomes lead. The first thing you see is how many missed concepts are now holding — not how many questions you answered.
- One best next focus, or a daily mix in 5, 10 or 18 questions. Everything counts the same.
- How warm your skills are — Warm, Cooling or Needs a refresh, never a rank.
Mistakes Notebook
Everything you have missed at least once, and how far each one has come.

Cooling · refresh in ~3dFor learners
Nothing you miss is ever lost.
- Every miss becomes a thread that moves one step along each time you answer it right.
- Twin questions — a fresh, unseen question on the same concept, so you prove the idea rather than a remembered answer.
- Spaced review brings a concept back when a check is most useful.
Skill Tree
Where you stand on each skill, chapter and topic — as of today.
- Holding well
- Came back after a miss
- Worth another look
- Early to say
- No misses so far
- Not started yet
For learners
Where you stand, in words — never a percentage.
- Chapters on the inner ring, topics outside, each in one plain state.
- An Upkeep view recolours the tree by what is warm, cooling or due a refresh.
- Your next step names one chapter and the topics worth practising — and opens exactly those.
Your practice, as a map
Each skill is a line. Each set you practised is a station on it.
- One sitting so far
- Building it up
- On track
- Mastered
- Set by your institute
For learners
Your practice, as a metro map.
- Each skill is a line and each practice set a station, coloured from Building it up to Mastered.
- A Board view places every set in a lane by where it stands now.
- Sets from your institute show as submitted — their results stay with your institute.
What has held
Concepts once missed, now right on a fresh question.
How you are using what you know

Illustrative data. Applying and new situations show for skills marked on the coverage page.
For learners
Not just what stayed — what you can use.
- What has held, by name — concepts once missed, now right on a fresh question.
- Applied on your own — how many of those you showed on a question that asks for more than recall, without a nudge.
- Used somewhere new — in a work situation, or asked a different way. Plain counts, never a percentage.

For trainers and institutions
A supervised checkpoint, read against practice.
- Entry and exit checkpoints, assembled from the evaluation bank so they are equally neutral for every cohort.
- Five observations per learner, per concept — a difference is a next step, never a suspicion.
- Sealed to the learner. They see “Submitted”; staff see what to revisit first.

For trainers and institutions
Per skill: applied, and used somewhere new.
- Beside what stayed, never combined with it — each reading with its own count and likely range.
- Measured where it can be, for skills whose questions are classified; the rest say “not measured yet”, never 0.
- The same counts go into the sponsor Impact Pack and the per-learner export.
Screens show illustrative example data, not real learners or cohorts.
Three ways to practise
Practise the way today feels.
Some days you know exactly what to work on. Some days you want the next step chosen for you. Some days you want to find out where you stand. Each way feeds the same picture of what you can do.
- Build your own setEvery planSkillChapterTopicLevel-matched
You choose. It matches the level.
Pick a skill, chapters or topics. Each next question is matched to how you are answering, and the match sharpens the more you practise — without ever showing you a rating.
Best when you know what you want to work on
Its debrief adds “Across this set”
- Personalised practiceEvery planDue to come backMissedReady to stretch
It chooses the next set for you.
A session built from your own practice: what is due to come back, what you missed and the idea behind it, and what is ready to be stretched. One tap, and the set is ready.
Best when you want the next step chosen for you
Its debrief adds “What came back”
- The ChallengerEvery planLet me ask that a different way.Both names point at the same list.
A partner that follows every answer.
One question at a time, as a conversation, with a character you name. Harder after two right on your own, the same idea asked another way after a miss — and at the end, where you stand, topic by topic.
Best when you want to find where you stand
Its debrief adds “What this Challenge found”
See a Challenge
Every way ends the same: one debrief — where to start next, what went well, where you stand topic by topic — plus what only that way can tell you, kept together in My Results with a private note. Rapid Fire rounds, Today's practice, practice groups and assigned sets are formats of the same practice and end the same way.
The Challenger
A practice partner that follows your answers to find where you stand.
The Challenger is built into Practicks — not a person, and not an AI judging you. It picks each question from how your last answer went, and ends with where you stand, topic by topic, and the one thing to practise next.
- Untimed, or timed your way — running out is never marked wrong
- A Reading & debugging focus: predict what code does, find what is wrong with it
- Pick its character and how it speaks — encouraging, straight to the point, or tough but fair
A cast of characters to choose from
On every plan
Nova · your Challenger
Built into Practicks · Python · Lists
The Challenger: Let’s find where you stand on Python. I’ll start in the middle and follow your answers.
You: b = a — so changing b leaves a alone.
The Challenger: You went for “the list is copied on assignment”. Plenty of people do. Let me ask that a different way.
You: Both names point at the same list — so both see the change.
The Challenger: That’s it. Back to where we were, with a new example. Take up to 90 seconds for this one.

Browse all skillsThe scientific pattern
A skill is treated as evidence over time.
Answer from memory, understand the feedback, and return for a later check — sometimes asked a new way. Practicks uses your practice answers to show what is holding, what you can apply and what deserves another look. Explore the principles below.
Six principles behind the practice. Open any one to see how it works.
Retrieval practiceBring what you know back to mind.
Answer practice questions from memory, then use feedback to check your understanding and guide your next attempt.
Spaced repetitionRevisit today. Recall more confidently later.
Practicks brings questions back at spaced intervals. Successful recall can lengthen the time before the next review; a miss gives you another opportunity to practise.
Level-matched practiceA challenge that adjusts with you.
When you build your own set, question selection responds to your answers to help match the challenge to your current ability.
Specific feedbackEvery answer deserves a “why.”
Review the explanation and specific feedback on your choices. Where a practice set offers nudges, each one helps you reason it out — it never hands over the answer.
Distributed practiceSmall sessions. More chances to recall.
Choose a manageable amount of practice and return over time, with room for breaks in between. You decide how much to do today.
Self-explanationMake your reasoning clearer.
In your Mistake Notebook, optionally put the idea into your own words and compare your reasoning with the explanation. Your self-explanation is private and does not change your score.
Research supports retrieval, self-explanation, spacing and feedback. Practicks uses these approaches, but it does not promise a particular learning outcome. Its signals are decision aids, not measurements of intelligence or a person’s worth.
For institutions
Everyone can tell you what was taught. Practicks keeps checking what stayed.
Training institutes, solo trainers and L&D teams get everything learners get — plus the tools to run cohorts and see what held, what was applied and what was used somewhere new. Practice stays safe for learners — no negative marking, a tip on every option. The evaluations you schedule keep their timing and results with authorised staff, separate from each learner’s own practice.
- Basic · practice only
- Institution · run cohorts
- Pro · evaluate and report at scale
Cohorts and programmes
Rosters, co-trainers, pinned skills and a lifecycle that starts and completes itself.
Cohort checkpoints
Entry and exit, sealed to the learner, compared with practice concept by concept.
Cohort Notes
Trainers share their own session board notes — an image, PDF or video — with one cohort. Written by your institution, never by Practicks.
Outcome reporting
Per skill: what has held, what learners applied on their own and what they used somewhere new — never one score. Plus a Sunday trainer digest and a sponsor-ready Impact Pack (Pro).
Source-to-Practice
AI drafts questions from your own material; a person approves each one. AI never scores a learner.
Integrity and oversight
Sandboxed coding, opt-in proctoring with consent, question-quality flags and a full audit trail.
Question coverage
Nine formats for different kinds of knowledge checks.
- Single answer
- Multiple answers
- True / False
- Fill in the blank
- Numerical
- Match the following
- Image hotspot
- Ordering
- CodingProgramming skills
Coding uses sandboxed execution on web, and is available in Evaluation only. Ordering supports code-construction sequencing for practice and mobile.
Clear boundaries
What Practicks is — and what it deliberately isn’t.
- Question-based practice and self-assessment for professional and technical skills.
- Self-assessment grounded in your own answers over time.
- Tools for training institutions to organise practice, evaluate and follow up.
Not a course or learning platform
No lessons or course material from Practicks, and no prescribed way to learn.
Not an exam or interview replacement
No claim of matching the pattern, timing or marking of any certification exam or hiring process.
Not a certificate or credential
Scores are feedback, not proof to submit to an employer or a certifying body.
Not a competition by default
Progress is personal. Opt-in group growth boards celebrate effort, not scores; scores are ranked only in live Rapid Fire rounds and on a group's shared assessments.
Build confidence one practice session at a time.
Choose what you want to strengthen, practise with feedback, and return later to check whether it still holds.
