## Flashcards (32 Cards)

| # | Front (Term / Prompt) | Back (Definition / Answer) | Example | Multiple-Choice Options |
| :--- | :--- | :--- | :--- | :--- |
| 1 | Summarize the 4 steps for executing a 'Final 72-Hour Exam Crunch' inside Flashcards.world. | 1. Raise deck Desired Retention to **93%–95%**; 2. Run the **`⚠️ Hard / Leech Cards`** filter in **Feynman + Writing Mode**; 3. Run a 60-card **Timed Multiple Choice (`⏱`)** simulation across all 6 modules; 4. Review **`⭐ Starred`** formula/triad cards on the evening before the exam. |  |  |
| 2 | What is 'Bury Related / Sibling Cards' during a daily review session? | When a single concept has both a Forward (`Front → Back`) and Reverse (`Back → Front`) card—or multiple Cloze siblings (`c1`, `c2`)—burying siblings delays the twin card until tomorrow so seeing Card 1 doesn't spoil Card 2 in the same session. |  |  |
| 3 | When is the 'Recently Added (Last 7 Days)' filter most useful? | Right after a week of heavy lectures or clinical rotations when you want to consolidate the newest 50–100 cards you created this week before they mix into your broader 2,000-card collection. |  |  |
| 4 | Why is 'Tag & Badge + Prompt to Refactor' better than silently auto-suspending leeches before an exam? | Because silently auto-suspending a card might hide a critical exam topic that you simply needed to split or study in Feynman Mode! |  |  |
| 5 | How do you 'Suspend' or 'Archive' a card during a review session if you realize you no longer need it for your exam? | Tap the card menu and select `Suspend Card`—which removes it from all future due queues immediately without deleting the card record in case you want to un-suspend it later. |  |  |
| 6 | How does the 'Hard Cards (`⚠️`)' filter identify which cards in your deck need urgent attention? | It selects cards with high FSRS-6 Difficulty ($D \ge 7.5$), cards recently rated `Again (1)` or `Hard (2)`, and flagged Leech cards that have lapsed repeatedly. |  |  |
| 7 | As you move the Desired Retention slider in FSRS-6 settings from 90% to 95% or 85%, what live preview does Flashcards.world show? | It immediately shows the estimated interval multiplier (e.g., `0.46× intervals / ~2.1× workload` at 95%, or `1.65× intervals / ~0.65× workload` at 85%) so you see the exact daily time impact before saving. |  |  |
| 8 | What is 'Custom Quiz Builder' in Flashcards.world? | A configurable practice exam engine where you pick the source deck(s), apply study filters (`⚠️ Hard`, `#tags`, level), choose question formats (Multiple Choice, Writing, Flashcard, True/False), set card count, and enable a strict per-card or total exam timer (`⏱`). |  |  |
| 9 | How does Flashcards.world automatically detect and badge 'Leech Cards (`⚠️`)' during your FSRS-6 reviews? | Whenever a card accumulates a high lapse count (e.g., ≥ 4 `'Again'` ratings) or its FSRS-6 Difficulty ($D$) climbs into the top difficulty tier, the app displays a visible **`⚠️ Leech`** badge on the card. |  |  |
| 10 | How do you simulate a realistic 60-question medical or legal board exam block using Custom Quiz Builder? | Select all 6 modules of your curriculum (192 cards), set Question Count = `60`, Mode = `Multiple Choice`, Shuffle = `On`, and Timed Exam (`⏱`) = `45s` or `60s` per question with answers reviewed at the end. |  |  |
| 11 | Where can you adjust your 'Desired Retention ($R_d$)' in Flashcards.world's FSRS-6 settings, and what range is supported? | In Study / Scheduler Settings, you can adjust Desired Retention along the slider from **75% to 97%** (with **90%** highlighted as the recommended default). |  |  |
| 12 | When a card shows the **`⚠️ Leech`** badge during study, what 3 one-click remediation tools does Flashcards.world give you right on the card? | 1. **Add/Edit `💡 Mnemonic`** (attach a memorable hook or analogy); 2. **Smart Split / Quick Edit** (break a bloated card into atomic pieces); 3. **Launch `🧠 Feynman Mode`** (diagnose and fix the underlying conceptual gap). |  |  |
| 13 | How do you read the 'Difficulty ($D$) Histogram' in your Deck Statistics? | If most of your cards cluster around $D \in [3, 6]$, your cards are well-formulated; if a large spike piles up at $D \in [9, 10]$, those cards are too bloated or ambiguous and should be refactored with Smart Split. |  |  |
| 14 | How can you filter your Deck Browser to see only cards that are 'Overdue right now' vs. 'Mature ($S \ge 21\text{d}$)'? | Use the status filter pills (`All`, `Due`, `New`, `Learning`, `Mature`, `Hard ⚠️`, `Starred ⭐`) at the top of the Deck Browser to inspect any slice of your deck instantly. |  |  |
| 15 | What happens if you click 'Reset to Default FSRS-6 Parameters'? | It restores the benchmark-validated global FSRS-6 21-parameter vector trained on hundreds of millions of reviews—which works with high accuracy even on brand-new accounts. |  |  |
| 16 | What is the difference between 'Resetting a Single Card's Progress' and 'Rescheduling a Card'? | Resetting returns a single card to `New` status (useful if you completely rewrote the card's content), whereas Rescheduling lets you set a target due window while preserving its FSRS-6 learning history. |  |  |
| 17 | What is 'FSRS-6 Parameter Optimization' in Flashcards.world once you have accumulated hundreds of review logs? | The optimizer analyzes your personal review history (`review_logs`) to fine-tune the 21 FSRS-6 parameters ($w_0 \dots w_{20}$) to your personal forgetting curve flatness and memory consolidation speed. |  |  |
| 18 | What is the 'Pre-Exam Confidence Score' displayed on a Topic Curriculum page? | An aggregate mastery indicator computed from the percentage of cards unlocked and the mean instantaneous Retrievability ($\bar{R}$) across all 192 cards in the 6-module curriculum. |  |  |
| 19 | How do you run an 'Interleaved Multi-Deck Session' across all 6 modules of a curriculum? | Click 'Study All Due' at the Topic or Folder level (or select all 6 modules in Custom Quiz) so FSRS-6 pulls due cards interleaved across `basic`, `intermediate`, and `advanced` sets. |  |  |
| 20 | How does the 'Study Heatmap & Streak Calendar' on the Flashcards.world dashboard help maintain daily consistency? | It visualizes your daily review activity over the past 365 days as a color-intensity grid (similar to a GitHub contribution graph), tracking your current streak, longest streak, and daily retention rate. |  |  |
| 21 | How does the 'By Tag (`#tag`)' filter let you study for a modular Friday quiz when all your cards live in one master course deck? | Select the specific lecture tags covered on Friday's quiz (e.g., `#lec07` + `#lec08`) in Custom Quiz / Filter Study to drill only those cards without splitting your master deck. |  |  |
| 22 | What is the 'Random Shuffle (`🎲`)' filter, and when should you use it? | It shuffles a random sample (e.g., 30, 50, or all cards) from your selected deck(s) regardless of due date—ideal for a final comprehensive mock-exam sweep 48 hours before test day. |  |  |
| 23 | How does the 'Response Time Tracker' per card help prevent spaced-repetition burnout? | Flashcards.world logs how many milliseconds you spend on each review (capped at 60s to ignore walk-aways), letting you sort your deck by 'Slowest Average Review Time' and split any card taking >20 seconds. |  |  |
| 24 | Why does Flashcards.world show you the card's live DSR stats (`D`, `S`, `R`, `Lapses`) in the card info drawer? | Inspecting a card's exact Difficulty ($D \in [1, 10]$), Stability ($S$ in days), and current Retrievability ($R\%$) lets power users see immediately why a card was scheduled today and how well it is consolidating. |  |  |
| 25 | What are the 5 built-in 'Study & Cram Filters' available in Flashcards.world when you want to run a targeted session outside your normal daily queue? | 1. **Hard / Leech Cards (`⚠️`)**; 2. **New / Unseen Cards Only**; 3. **Recently Added (Last 7 Days)**; 4. **By Tag (`#tag`)**; 5. **Random Shuffle (`🎲` Cram All)**. |  |  |
| 26 | What analytics charts are available in the 'Deck & Memory Statistics' dashboard? | 1. **Card Maturity Breakdown** (New vs. Learning vs. Young $S < 21\text{d}$ vs. Mature $S \ge 21\text{d}$); 2. **Future Due Forecast** (bars showing reviews due over the next 30 days); 3. **Retrievability & Difficulty Distribution histograms**; 4. **True Retention % by week**. |  |  |
| 27 | How do you read the 'Future Due Forecast' chart when planning a weekend trip? | The forecast bar chart shows exactly how many cards will fall below $R_d = 90\%$ on each upcoming day over the next 30 days, allowing you to use 'Review Ahead' before a trip. |  |  |
| 28 | How does 'Review Ahead (Study Before Due Date)' work in Flashcards.world without breaking FSRS-6? | When you review cards 1–2 days ahead of a flight or busy exam week, FSRS-6 calculates their exact current Retrievability $R(t, S)$ (e.g., $R = 93\%$) and scales the stability gain proportionally—never over-inflating intervals. |  |  |
| 29 | How do you configure 'Daily New Cards Limit' and 'Maximum Daily Reviews' in Flashcards.world? | In Deck / Scheduler Settings, set your target `New Cards / Day` (e.g., 20/day) and `Max Reviews / Day` cap so your daily queue stays predictable and never overwhelms your schedule. |  |  |
| 30 | Why does Flashcards.world cap recorded per-card review duration at 60 seconds when you leave a tab open? | So if you get a phone call or step away from your desk mid-card, a 20-minute idle pause does not distort your study time statistics or analytics. |  |  |
| 31 | How does the 'Leech Auto-Action' setting work if a card hits 8+ lapses? | You can configure Flashcards.world to **Tag & Badge Only (`⚠️ Leech`)** (recommended, prompting you to add a mnemonic or split the card) rather than silently hiding the card without your knowledge. |  |  |
| 32 | Can you set a different Desired Retention for an upcoming 'High-Stakes Exam Deck' (93%) vs. a casual 'Lifelong Trivia Deck' (84%)? | Yes—Desired Retention can be configured globally or overridden per deck/preset so your urgent exam decks stay above 93% retrievability while lifelong maintenance decks stay effortless. |  |  |
