Let an attempt guide the next study block.

A diagnostic is useful when it changes the plan. Here, formula selection gets more attention than facts already recalled correctly.

App tools · WORKED EXAMPLE

A 10-minute diagnostic finds that your chemistry recall is sound, but you choose the wrong formulas in physics. How could you use the remaining 50 minutes?

ANSWERLet the gap choose the practice

Prepared example for learning.

  1. 1

    Identify the decision behind the errors

    Check whether the physics mistakes come from choosing a relationship, interpreting the quantities or doing the arithmetic. Here, formula selection needs attention.

  2. 2

    20 minutes: rebuild the relationships

    Review what each relevant formula connects and when it applies. Explain the quantities and assumptions before substituting values.

  3. 3

    20 minutes: mix fresh questions

    Attempt problems that require different relationships. Choose and justify a formula without seeing a heading that gives it away.

  4. 4

    10 minutes: retest and record

    Try a new question unaided. Note any unresolved decision for your next session; one successful retest does not establish mastery of the whole topic.

Try it in Lirno

Let your attempt choose the next review.

Bring your assessment topics to Lirno’s Exam Coach. Use a short diagnostic to find a gap, practice that skill and check it with a fresh question.

Start here

Diagnose the gap. Practice it. Retest.

  1. 01

    Define the scope

    Use the syllabus, revision list, and assignment feedback.

  2. 02

    Diagnose with practice

    Attempt representative questions before choosing what to reread.

  3. 03

    Repair and retest

    Explain the missing concept, practice it, and check again with a new task.

Start from the actual assessment

Build a topic list from the syllabus, teacher guidance and the format of the test. Identify whether you need to recall facts, choose a calculation method, interpret data or write an extended explanation. Practice should reflect what the assessment asks you to produce.

Give Lirno that context when requesting revision help. A generic set of questions on a subject may include material outside your current course or miss the skill you need to demonstrate. Keep the official assessment information as the reference.

Try a short diagnostic before opening the notes

Attempt a few questions across the topics and record where you hesitate. Lirno Exam Coach uses a diagnose, practice and retest workflow to help focus revision. The initial attempt gives you evidence about what needs attention, rather than choosing a topic only because it feels familiar.

Separate a forgotten definition from an incorrect model or an arithmetic slip. Those mistakes need different practice. Ask for feedback on the decision behind a wrong answer so the next study block targets its cause.

Choose a repair from the kind of error

Three wrong answers can need three different reviews. If you divide distance by the wrong interval, practice selecting the start and end times. If you use speed where a task asks for velocity, compare distance and displacement. If your setup is correct but 150/30 becomes 0.5, use an estimate and check the division.

Keep a small record: question type, first wrong decision, repair and a fresh retest. For an essay, replace the numerical categories with claim, evidence and explanation. Choose representative questions from the actual assessment scope. A short diagnostic helps allocate review time, but it does not establish mastery of every topic from one sample.

Mix questions when choosing the method matters

A run of nearly identical exercises can let you use the same procedure without deciding whether it fits. When your assessment requires method selection, mix a few relevant question types and identify the structure before calculating. Explain why a particular approach applies.

Use quizzes or short written answers to practice the skill your course expects. Check generated questions against your material, and include enough context for diagrams and data. Keep review manageable so you can investigate the mistakes rather than only collect a score.

Retest after a break and adjust the plan

Try a fresh question after time away from the explanation. Compare your decision and reasoning with the earlier attempt. If the same gap returns, narrow the next practice instead of simply rereading the whole chapter. Record what is now clear and what still needs work.

Lirno activity and study tools can support this routine. Treat progress information as feedback about the work you have done, not a prediction or guarantee of an exam result. Keep your plan realistic and aligned with the time remaining.

Check coverage as well as recent mistakes

A diagnostic can miss a topic it never sampled. If the assessment includes equations, graphs and written explanations, a strong result on three equation questions does not establish readiness for the other formats. Make a coverage list from the actual syllabus and include at least a representative task for each required type as you plan the review.

Keep two records: what you attempted and why an answer failed. “Graphs not sampled yet” is different from “graph gradient misunderstood.” Reserve a short first attempt for the unsampled area, then use the response to choose the repair. That prevents a targeted plan from becoming a plan that overlooks required material.

Your next small win

Let the attempt choose the review.

Begin with a short question from the topics in your assessment. Inspect the first decision that failed, then choose practice that addresses that cause. A completed review session is useful context; a new independent attempt tests the repair.

Prepared mini exercise

You answered three algebra questions correctly, but your test also includes graph interpretation and written explanations. What can the diagnostic establish?

Give me a hint

Compare the types of task sampled with the types the assessment requires.

Show the reasoning

It provides evidence about those three algebra attempts. It has not sampled graphs or written explanations. Add a representative question from each unsampled type, then use the first incorrect decision to choose a focused repair.

Make it yours

Carry the idea into your own homework.

Make a coverage list for your assessment. Mark each area as unsampled, attempted with a specific gap, or attempted successfully. Use that list alongside your recent mistakes to choose the next practice block.

Catch it before it trips you up

Three small details.
A stronger attempt.

Inspect the part of the method that this exercise actually tests. These are the three errors to check first.

01

Reviewing every topic equally

A short diagnostic attempt can reveal where time is needed. Use the evidence from your actual questions, while checking that the planned review still covers the required assessment topics.

02

Retesting the memorized example

An unchanged question may test recall of its answer. Use a nearby problem with new values or conditions to find out whether you can choose and explain the method again.

03

Reading a score as a guarantee

A practice score describes that attempt. Inspect the reasoning and conditions as well as the total, then use another independent question to assess what still needs attention.

Try a different case

Same idea.
A new decision.

Make an attempt before opening the explanation. These original tasks test a different part of the method, so a familiar answer alone will not be enough.

01

Diagnose before choosing revision

In a right-triangle question with hypotenuse 13 and leg 5, you correctly write b² = 169 − 25 but report b = 144. Which skill needs a repair?

Compare your reasoning

The model and subtraction are correct. The missing operation is taking the positive square root: b = √144 = 12.

Practice distinguishing b² from b, then try a fresh triangle with hypotenuse 10 and leg 6: b² = 100 − 36 = 64, so b = 8. Relearning the entire theorem would overlook the specific error.

Keep this clue: Distinguish choosing the relationship from completing its algebra.

02

Retest with a changed question

You memorized that a $60 item with 20% off costs $48. Which new question tests the same percentage relationship more usefully?

Compare your reasoning

Try: “A $50 item has 30% off. Find the sale price and explain which amount the percentage uses.”

The reduction is 0.30 × 50 = $15, so the sale price is $35. Explain that the reduction uses the original $50. That checks a method instead of recalling the previous $48 result.

Keep this clue: Vary values while keeping the skill clear, then broaden the task when the basic repair holds.

FAQs

Questions about Exam preparation

Can Lirno predict exam questions?

Do not treat AI-generated practice as an exam prediction. Use your teacher’s scope and course materials to choose what belongs in revision.

What does Exam Coach help with?

Lirno’s Exam Coach supports identifying weak topics, targeted practice, and retests within a study workflow.

Is a correct answer enough?

Check that you can explain the method and apply it to a different question. A correct guess provides less evidence than justified working.

Does this guarantee a better grade?

No. Results depend on many factors. Use the tools for practice and feedback without treating them as a guarantee of performance.
