বাংলা শিক্ষা User Guide

🚀 Getting Started

The app has six tabs in the navigation bar:

If you're a complete beginner, start with the Alphabet tab — the app will introduce letters in waves and quiz you on them as you go. If you already know some Bengali, take the placement test to skip ahead. After your first session, check the Today tab each day to see exactly what's due.

📋 Today Tab

The Today tab gives you a single answer to "what should I study right now?" It assembles a daily plan from three sources:

At the bottom of the screen you'll also see today's XP total and your current streak at a glance.

Review badge

When items are due for review, a numbered badge appears directly on the Today tab label in the navigation bar, and a prominent 🔔 Reviews due — Start now alert card appears at the top of the Today screen. Tapping either one launches the review session immediately, without having to navigate anywhere else.

🔤 Alphabet

Bengali has 50+ characters, divided into three types:

Wave-based learning

Letters are introduced in waves of 5 through the Mixed Practice module. Each wave has two phases:

1. Teach — You see each new letter as a flashcard with its name, pronunciation, IPA sound description, and an example word.
2. Quiz — 8 questions mixing the new letters with ones you've seen before.

The next wave unlocks once enough letters from the current wave reach mastery level 2. This pacing keeps the workload manageable.

Individual module practice

Each letter group (Vowels, Velar Consonants, Palatal Consonants, etc.) also has its own module card you can open for targeted practice. These run standalone quizzes on just those letters.

Conjunct Consonants (যুক্তবর্ণ)

The 🔗 Conjunct Consonants module covers 32 compound letter combinations — two consonants fused together into a single glyph. These appear constantly in everyday Bengali text and are essential for fluent reading. Examples:

The module uses the same quiz types as base consonants (name MC, sound MC, name FIB, romanized FIB) and integrates with the mastery and spaced-repetition system. Grammar Lesson 16 covers conjunct consonants in depth — study that lesson alongside this module for the best results.

Writing Practice (canvas)

On any letter flashcard inside a learn module, tap the ✏️ Practice button to open the writing canvas. The Bengali character is shown faded in the background; draw over it freehand with your mouse or finger to practice the stroke shape. Below the canvas, numbered stroke hints appear with short tips describing how to draw each part of the character — useful when you're not sure where to start. Tap Clear to wipe the canvas and try again. There is no stroke-order checking — the canvas is a free-form scratchpad for building muscle memory.

Keyboard shortcuts work while the canvas is open:

Matra Drills (া–ৌ)

Bengali vowel signs (মাত্রা / matra) are diacritics that attach to a consonant to change its vowel sound — for example কা (ka), কি (ki), কো (ko). The Matra Drills module (🔡) covers all 9 matras combined with 5 representative consonants — 45 combinations in total. Each quiz question shows the combined glyph and asks you to identify or type its romanized sound (e.g. type che for চে). This module pairs well with Grammar Lesson 15, which explains the matra system in detail.

Listening Practice

The Listening Practice card (🎧) at the bottom of the Alphabet home runs audio-only versions of the letter quizzes — you hear a letter sound and must identify it or type its romanized form, without seeing the Bengali glyph. This builds the ear-to-script connection that reading-focused practice alone can't develop.

Full Alphabet Chart

The Full Alphabet Chart module (📊) shows all letters at a glance, color-coded by your current mastery level so you can see where you still have gaps.

Question types

📖 Vocabulary

The vocabulary section covers 5,278 words — from the most common everyday expressions down to intermediate vocabulary across 26 topic areas.

Categories

Mixed Practice — the main learning mode

The Mixed Practice card (🧠) is the recommended way to build vocabulary. It introduces words in frequency order — starting with the 20 most common Bengali words and gradually working through the full 5,000+ corpus.

• Words are introduced in waves of 10, with 5 shown as flashcards before each quiz.
• The curriculum interleaves words across categories, so you never study just one topic for too long.
• The next wave unlocks when enough words reach mastery level 2.

Category practice

Each category card runs a focused quiz on words from that topic only — useful for drilling a specific area or preparing for a trip.

Browse All Words

The Browse All Words card (🔍) lets you search and explore the full dictionary. You can:

• Search by Bengali script, romanization, or English meaning
• Filter by category
• Tap any word to see its full entry: pronunciation, part of speech, and an example sentence
• In a word's detail card, tap 🔊 Word to hear just the word, or 🔊 Example to hear the full example sentence read aloud — useful for hearing the word in natural sentence context
• Tap + Study next to any search result to add that word to the front of your Mixed Practice queue without having to open its detail card first — a fast way to queue words you encounter while browsing
• Tap + Study this word inside a word's detail card for the same effect

Question types

Wrong-answer feedback

When you get a vocabulary question wrong, the feedback bar shows the correct answer and the word's example sentence in context — so you can see the word used naturally right away.

📝 Grammar

36 lessons take you from basic sentence structure through advanced topics (causative verbs, passive constructions, honorific register), a dedicated pronunciation/sound-change guide, and five graded reading passages. The first 30 lessons teach grammar concepts; the later lessons extend that foundation with practical reading.

Lesson list

Conjugation reference table

At the top of the Grammar home there is a collapsible Bengali Verb Conjugation table (tap to expand). It shows common verb endings for every subject pronoun across four tenses — present, past, future, and continuous — in a single compact grid. Use it as a quick reference while working through the grammar lessons or when you encounter an unfamiliar verb form.

Reading passages (Lessons 32–36)

Each reading passage lesson presents a short Bengali text — between two sentences and a full letter — at a difficulty level matched to the lesson number. Inside each lesson:

• The Bengali text is shown first, unsupported — read as much as you can without help.
• Tap ▼ Show romanization to reveal the phonetic transcription.
• Tap ▼ Show English translation to reveal the full translation.
• Example cards highlight key vocabulary and grammar patterns used in the passage.
• The quiz tests reading comprehension with multiple-choice and fill-in-the-blank questions about the passage.

How lessons work

Each lesson card shows a short explanation followed by a quiz. Lesson quizzes use four question types:

• Word order: Arrange tiles into the correct Bengali sentence
• Translation MC: Choose the correct translation from four options
• Error spot: Identify which sentence is grammatically correct
• Fill-in-the-blank: Type the missing word or phrase

Wrong-answer feedback

When you answer a grammar question incorrectly, the feedback shows the correct answer. For fill-in-the-blank and word-order questions, it also shows any additional explanation attached to that question, so you understand why that answer is correct — not just what the correct answer is.

🔢 Numbers

The Numbers tab (সংখ্যা) teaches Bengali numeral glyphs and the spoken words for numbers. It has four modules:

Numeral Glyphs (০–৯)

Signs, currency notes, and printed documents in Bangladesh use Bengali numerals alongside or instead of Arabic digits. This module shows you each digit glyph and asks you to name it or type its romanized pronunciation. The quiz is identical in format to the Alphabet quizzes — multiple-choice name, multiple-choice sound, name fill-in-the-blank, or romanized fill-in-the-blank.

Number words

Bengali has a complex counting system with distinct words for every number from 1–99 — unlike English, where you just combine tens and ones. The three word modules introduce these in groups, starting with the most frequent. Question types:

🗣️ Common Phrases

The Phrases tab teaches 144 high-utility conversational phrases organized into 12 real-life situations. Unlike the Vocabulary section — which teaches individual words — Phrases teaches whole expressions you can use immediately in conversation.

Situations covered

How the Phrases tab works

The hub screen shows a grid of situation cards, each with a progress bar showing how many phrases you've mastered. Tap any unlocked situation to open its flashcard view, then start a quiz.

1. Flashcard view — Browse through all 12 phrases in a situation one at a time. The front shows the Bengali script; tap to flip and reveal the romanization, English meaning, and any cultural notes. Phrases that have a natural reply also show it on the card back, so you can see how the exchange flows.
2. Situation quiz — Tap Start Quiz → to practice just that situation (up to 12 questions).
3. Mixed Practice — The card at the top of the hub draws from all your unlocked situations, prioritizing phrases you haven't seen or have answered incorrectly.

Question types

The Dialogue question type

Dialogue questions are unique to the Phrases module. Instead of translating an isolated phrase, you're shown a conversational opener and must choose the most natural response:

Dialogue questions only appear for phrases that have a defined reply, and only once you've seen a phrase at least once (mastery ≥ 1). Wrong-answer distractors are drawn from elsewhere in the phrase bank, so you're also passively reviewing other phrases as you choose.

Wave unlock

Situations unlock one at a time in a fixed order, starting with Greetings. Each new situation unlocks once you've answered at least 60% of the previous situation's phrases correctly enough to reach mastery level 2. The 🔒 icon on a card disappears as soon as it unlocks.

⭐ Mastery & Spaced Repetition

Every letter, word, and grammar item you study has a mastery level that tracks how well you know it:

• Answer a question correctly → level goes up by 1
• Answer incorrectly → level drops by 1

Review Due

When any mastered item is due for review, a 🔔 Review Due (N) button appears in the tab bar. Tapping it runs a mixed review session covering alphabet letters, vocabulary words, and grammar items that have passed their review interval.

The Today tab also shows your review count at the top of the daily plan, with a direct button to start the session.

Keeping up with reviews is the key to long-term retention — the spaced repetition schedule spaces them out so you review items just as you're about to forget them.

🎯 Placement Test

Already know some Bengali? The placement test assesses your existing knowledge and sets your mastery levels accordingly, so you can skip content you already know.

The test has three stages (~30 questions total):

After the test, you'll see a results breakdown by stage and can choose to apply the results or start fresh. You can retake it anytime from Settings → Retake Placement Test.

⚙️ Settings

Open settings by tapping the ⚙️ button in the top-right corner of the app.

FIB Answer Mode

Controls how you type answers in fill-in-the-blank questions:

The on-screen Bengali keyboard (বাং ▲ button) is available in all FIB input fields regardless of mode.

Quiz Modality

Controls whether audio is used in quizzes:

Slow audio: On listening questions, a 🐢 button appears next to the play button. Tap it to toggle half-speed playback (0.5× vs. the default 0.85×) — useful if the speech is too fast to catch individual sounds. The setting stays on until you tap it again.

Note on audio quality: Pronunciation is generated by your browser's built-in text-to-speech (TTS) engine using the bn-BD voice. Quality and accent vary by browser and operating system — Chrome on Android typically gives the best Bengali TTS. If you don't hear audio, your device may not have a Bengali voice installed; check your system's language/speech settings.

Advanced

The Advanced section in Settings contains the 🐢 Slow Audio toggle. When enabled, all TTS playback uses half-speed (0.5×) instead of the default 0.85×. This is a persistent, app-wide setting — unlike the per-question 🐢 button on individual listening cards, this toggle keeps slow audio on for the entire session and across restarts until you turn it off again.

Themes

11 color palettes inspired by Bengali culture and geography, each available in light and dark mode. Switch light/dark with the ☀️ button.

👤 Profiles & Progress

Multiple profiles

The app supports multiple user profiles, each with completely separate progress. This is useful for households where multiple people share a device, or for keeping a "study" profile separate from a "casual" one.

Switch profiles or create a new one from Settings → Switch Profile.

Renaming a profile

Each profile card in the profile picker has a ✏️ rename button. Tap it, enter a new name, and confirm. The profile name must contain only letters, numbers, spaces, or hyphens.

Statistics

Tap 📈 Statistics in Settings to see a detailed breakdown of your progress:

• Summary cards: Total XP, day streak, letters/words/lessons mastered
• Activity heatmap: 13 weeks of daily XP history
• Mastery breakdown: Progress bars for Alphabet, Vocabulary, Grammar, Phrases, and Conjunct Consonants
• Vocabulary by category: See which topic areas you're strongest and weakest in
• Letter grid: All 50+ letters colored by mastery level
• Achievements: All 10 badges with earned/unearned status

Export & import

Back up your progress anytime from the profile picker. Each profile card has two export options:

• ⬇ Download — saves a JSON file to your device. This is the recommended backup method.
• 📋 Copy to clipboard — copies the same JSON to your clipboard, useful for pasting into a note or email.

When you tap Download, a filter dialog lets you choose what to include in the export: All data, or just one module — Alphabet, Vocabulary, Grammar, or Phrases. This is useful for sharing just your vocabulary progress without exporting everything.

To restore on another device or browser, use Import Progress in Settings. This is the recommended way to move your data between devices.

Progress adjustment

If the placement test set something wrong, you can fine-tune individual mastery levels from Settings → Adjust Progress.

🏆 XP, Streaks & Achievements

XP (Experience Points)

You earn XP for every question you answer correctly. FIB questions are worth slightly more than multiple choice (15 vs 10 XP) because they require active recall. Your total XP is shown in the top navigation bar (⭐).

Streaks

A streak counts the number of consecutive days you've done at least one quiz. Your current streak is shown in the nav bar (🔥). The streak bar below the nav fills up toward 7 days.

Achievements

A toast notification pops up the moment you earn a new badge. View all your badges in the Statistics panel.

⌨️ Keyboard Shortcuts

Quiz shortcuts

Key hints are shown on multiple-choice buttons in the app (e.g. [1], [2]) so you can always see which key maps to which option.

Writing canvas shortcuts

These keys are active whenever the writing practice canvas is open:

🔡 Romanization Guide

The app uses a consistent romanization scheme throughout. Here are the most important symbols:
