Should I reset my Anki deck when I have thousands of overdue reviews?

No! Resetting cards to "New" erases all previous memory stability calculations. You lose months of algorithmic tracking and force yourself to re-learn cards you already know cold. Instead, use the descending-interval filtered deck method to clear your backlog systematically.

What is the best search filter for an Anki backlog deck?

In Anki Desktop, press "F" to create a Filtered Deck. In the search filter box, type: "is:due prop:due<=-1". Under "Order", select "Decreasing intervals". This ensures you review mature cards with the highest memory stability first.

Should I keep doing new cards while catching up on a backlog?

Never. Adding new cards while in a review deficit compounds review overload. Freeze new cards by setting your deck options New Cards/Day to 0 until your overdue backlog is completely eliminated.

What should I do with cards I keep failing during my backlog clearance?

Any card you fail repeatedly (4+ lapses) is a chronic leech. Suspend it immediately. You can re-learn the underlying concept later using a textbook or clinical vignette question bank like Penziv.

Recommended 4-Step Recovery Protocol

1Freeze New Cards: Set your deck options New Cards/Day to 0 until the backlog is cleared.
2Create Descending Filtered Deck: Press F in Anki, filter by is:due prop:due<=-1, and sort by Decreasing intervals.
3Do Daily Due First: Review today's cards, then complete exactly 100 cards from your backlog deck.
4Suspend Leeches: If a card has failed 4+ times during recovery, suspend it without guilt.

The Psychology of Review Dread

Why Big Backlogs Paralyze Students (And How Math Solves It)

When students see thousands of due reviews, the cognitive burden of anticipated failure causes avoidance behavior. Days turn into weeks, and the backlog grows exponentially.

By isolating overdue cards into a separate filtered deck sorted by descending intervals, you guarantee a high initial success rate (>85%). Seeing tangible progress in 20-minute timed bursts breaks the psychological dread and restores study momentum.
