2026 Quick-Reference Cheat Sheet & Benchmark Table: SM-2 Spaced Repetition (Anki), Weighted GPA & Pomodoro Studio

Quick Answer & 2026 Technical Summary (spaced repetition interval gpa calculator)Updated 2026 Standard

In SM-2, after the initial learning steps (`I(1) = 1 day`, `I(2) = 6 days`), subsequent intervals are computed as `I(n) = round(I(n-1) × EF)`, where `EF` is the card's Ease Factor (starting at `2.50` or `250%`). Rating a card affects `EF` via `EF' = EF + (0.1 - (5 - q) × (0.08 + (5 - q) × 0.02))`, clamped at a minimum of `1.30`.

How to Use SM-2 Spaced Repetition (Anki), Weighted GPA & Pomodoro Studio

01

Simulate SM-2 Flashcard Reviews in the Spaced Repetition Lab

Click 'Again (1)', 'Hard (2)', 'Good (3)', or 'Easy (4)' to watch the SM-2 algorithm update the card's interval (days), Ease Factor (`2.50`), and retention curve.

02

Add Your Courses, Credits & Tiers in the GPA Calculator

Enter each course's letter grade (`A+` through `F`), credit hours, and level (`Regular`, `Honors +0.5`, `AP/IB +1.0`) to calculate both Unweighted and Weighted GPA.

03

Solve for Your Required Final Exam Score

Input your current class percentage, desired final grade target, and final exam weight (`10%–50%`) to see the exact exam score needed.

04

Launch a 25/5 or 50/10 Pomodoro Study Sprint

Start the built-in Pomodoro timer to execute focused active-recall blocks directly inside the studio.

Key Capabilities & Technical Architecture

SuperMemo SM-2 & Anki Ease Factor (`EF`) Interval Simulator

Step through flashcard review sequences (`Again`, `Hard`, `Good`, `Easy`) to visualize how Ease Factor (`EF >= 1.3`) and interval multipliers prevent Ebbinghaus forgetting decay.

Weighted (5.0 AP/IB, 4.5 Honors) & Unweighted (4.0) GPA Engine

Compute cumulative and semester GPA across standard, Honors (+0.5), and AP/IB/Dual-Enrollment (+1.0) courses with credit-hour weighting.

'What Do I Need on the Final Exam?' Target Grade Solver

Calculate the exact minimum percentage required on a weighted final exam (`w%`) to lock in an A (90%/93%), B (80%), or passing threshold.

Live Deep-Work Pomodoro Timer (25/5 & 50/10 Ultradian Cycles)

Run distraction-free study intervals with automatic short/long break transitions and session velocity tracking.

Practical Use Cases

Escaping Anki 'Ease Hell' & Optimizing Exam Deck Schedules

See mathematically how repeatedly pressing 'Hard' permanently drops a card's Ease Factor by `-0.15` (`15%`) and how to pace daily new cards before a test date.

Planning High School AP/IB & University Semester GPA Targets

Compare unweighted 4.0 admissions metrics against 4.5/5.0 weighted transcripts and test how a single 4-credit STEM course shifts your cumulative GPA.

Triage During Finals Week Using Exam Weight Math

Determine which final exams have the highest mathematical leverage on your letter grades so you allocate Pomodoro blocks where they matter most.

Frequently Asked Questions (FAQs)

How does the SuperMemo SM-2 algorithm used by Anki calculate the next review interval?+

In SM-2, after the initial learning steps (`I(1) = 1 day`, `I(2) = 6 days`), subsequent intervals are computed as `I(n) = round(I(n-1) × EF)`, where `EF` is the card's Ease Factor (starting at `2.50` or `250%`). Rating a card affects `EF` via `EF' = EF + (0.1 - (5 - q) × (0.08 + (5 - q) × 0.02))`, clamped at a minimum of `1.30`.

What is 'Ease Hell' in Anki and why does FSRS fix it?+

In classic Anki SM-2, pressing 'Hard' reduces a card's Ease Factor by `0.15` (`-15%`) and pressing 'Again' reduces it by `0.20` (`-20%`), while pressing 'Good' leaves Ease unchanged (`+0.00`). Over months, difficult cards sink to the `1.30` floor and flood your daily queue. Modern FSRS (Free Spaced Repetition Scheduler) replaces static ease penalties with a three-component DSR (Difficulty, Stability, Retrievability) memory model.

What is the mathematical formula for Required Final Exam Grade?+

If your current course grade is `C`, the final exam is worth weight `w` (expressed as a decimal from `0` to `1`), and your target overall course grade is `T`, the required final exam score `F` is: `F = (T - C × (1 - w)) / w`.

What is the difference between Unweighted GPA and Weighted GPA?+

Unweighted GPA maps all courses to a strict `4.0` scale (`A = 4.0`, `B = 3.0`, `C = 2.0`) regardless of course difficulty. Weighted GPA adds quality-point bonuses for advanced rigor—typically `+0.5` for Honors (`A = 4.5`) and `+1.0` for AP, IB, or Dual Enrollment (`A = 5.0`)—weighted by each course's credit hours.

Why does combining Active Recall with Pomodoro outperform passive re-reading?+

Cognitive psychology research (Roediger & Karpicke's testing effect) shows that actively retrieving information from memory strengthens synaptic retrieval pathways far more than passive highlighting, while 25-to-50-minute Pomodoro boundaries prevent vigilance decrement and working-memory saturation.
