The sidebar

Practice (home), Assignments, History (every past practice), Study (notes, summaries & flash cards), Bookmarks (questions you saved) and Reports (your analytics). + Create practice starts a new practice any time.

Accept your teacher's invitation

When a teacher adds you, an invitation card appears on your home page. Press Accept — from then on the teacher can assign you work and see your results for those assignments.

Start an assignment

The Assignments page lists everything assigned to you with question counts and time limits (a Late tag marks overdue ones). Press Start now — a summary sheet shows the subject, number of questions, time limit, who set it, and the due date. Press I'm ready! to begin.

1 · Pick the subject

Recent subjects puts the ones you use most first; All subjects opens the full catalogue for your curriculum (HKDSE, IGCSE, IB, A-Levels and more).

2 · Choose chapters — or upload your notes

Pick the practice language, then tick the chapters you want to drill. Prefer to practise from your own materials? The Upload Materials tab takes notes, e-books or past papers, and AI generates questions matching their scope, style and difficulty.

3 · Difficulty

Five levels from Easy to Master. Pick where you are today — you can always level up next time.

4 · Time limit & question mix

Optionally set a time limit (15–120 min), choose how many multiple-choice, short and long questions you want, and press Generate by AI.

Multiple-choice questions

Tap an option to answer — the progress rail marks it Answered. Use Prev / Next or tap any question number in the rail to jump around. Math renders beautifully, including equations.

Swap a question you don't like

The 🔄 Change Question icon regenerates the current question — the AI replaces it with a fresh one from the same chapter. The 🚩 icon reports a faulty question and AI fixes it immediately.

Written questions: type, photograph or hand-write

Short and long questions accept three input styles:

• Type in the rich-text editor (with a math formula tool).
• Upload your answer — photograph work you did on paper; the system reads it automatically.
• Write your answer — open a handwriting canvas and write with your finger, stylus or mouse.

The handwriting canvas

Write naturally — pen, eraser, undo and redo tools sit in the toolbar. Equations are welcome.

Handwriting becomes editable text

Press the ✓ tick and OCR converts your handwriting — equations included — into editable text in the answer box. Tap the equation afterwards to fine-tune it before submitting.

Submit

Press Submit — a summary confirms how many questions you've answered. Confirm, and the AI marks everything at once: multiple-choice instantly, written answers graded against the model solution with written feedback.

Your grade and AI insights

The result page shows your grade (mapped to your curriculum's scale, e.g. HKDSE 1–5) and score, followed by Insights** — AI-written analysis of your strengths, weaknesses and exactly what to fix next. Swipe through the cards.

Every question, fully explained

Open any question to see your answer, the correct answer and a step-by-step Solution. For written questions the AI also leaves a comment on your working — what you did well and what to improve.

Performance by chapter

The Chapters tab groups your score by topic so you can see which chapters held you back.

Practise similar questions

Struggled with one question? The 🔁 Repeat Question button generates a fresh practice full of similar questions — choose the amount and a time limit, then Generate by AI.

Report a question

Think a question is faulty or the marking unfair? Press 🚩 Report Question, describe the issue, and AI reviews it immediately — it can correct answers, re-mark, or improve the solution.

Print, redo or delete

The ⋯ menu offers Print Practice (with or without solutions — great for offline revision), Redo Practice (retake the same questions) and Delete Practice.

Your full history

History keeps every assignment and practice you've ever done, grouped by date with scores and grades. Tap any entry to revisit its result, answers and solutions.

Browse subjects & chapters

Choose your curriculum once, and every subject appears with its full chapter list. Recent chapters and subjects float to the top for quick access.

Chapter notes

Every chapter has friendly, thorough Notes written for self-study — concepts, worked examples and mnemonics, with full math rendering. Use the 🌐 button to switch the notes' language.

Summaries for quick revision

The Summaries tab condenses the chapter into key points — ideal right before a test.

Flash cards

The Flash Cards tab lists question-style cards for the chapter, each tracking your mastery. Press the floating card button to start a review session.

Start a review session

The floating card button opens the session builder — pick the practice language and any mix of chapters (or Select all), then Next to build your deck.

Self-testing with flash cards

Read the front, think of the answer, then Tap to flip. Mark yourself honestly with Know / Don't know — the session summary tells you when to review again to keep the knowledge fresh (spaced repetition).

Session completed

Finish the deck to see your session stats. Practice now turns the same chapter into a full AI practice on the spot.
