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.

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.

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.

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!

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.

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.

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.

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 (`⏱`).

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.

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.

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).

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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)**.

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**.

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.

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.

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.

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.

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.

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.
