November 2024 and 2025 bulletin data
Two November sessions of worldwide results are now available throughout IB Predict.
- Kept all six diploma groups visible in the sidebar summary, using a dash for subjects that have not been selected yet.
- Weighted grade probability toward recent post-COVID November boundaries, followed by recent May boundaries, while reducing the influence of transitional and older sessions.
- Changed grade probabilities to reflect actual outcomes across comparable published session and timezone boundaries, eliminating misleading 50/50 results at forecast cutoffs.
- Treated TOK and Extended Essay boundaries as stable cutoffs, removing artificial 50/50 probabilities when a score lands exactly on a threshold.
- Shortened the forecast table heading in the predicted-grade card to “November 2026 forecast.”
- Reworked the individual subject result card to show the forecasted grade probability alongside one grade below and above, plus a shorter N25 percentile comparison.
- Made the November 2026 forecast the default boundary choice on individual subject pages, with official M25 and N25 boundaries available as clear alternatives and no competing result card.
- Focused each main-calculator subject card on one best next move, moving percentile standing, grade outlook, assessment calculations, and session history into optional context.
- Replaced decimal average grades in chart summaries with a plain typical whole-grade result, keeping the exact published average inside the optional chart explanation and data table.
- Clarified forecast percentages by stating the fixed weighted score first, separating the most likely grade from its likelihood, and keeping model details optional.
- Kept unpersonalized diploma benchmarks out of the incomplete sidebar, placing session averages, pass rates, and sample sizes inside optional comparison details.
- Reduced the Next grade panel to one actionable recommendation, moving boundary risk, assessment calculations, and past-session comparisons into optional details.
- Clarified historical boundary charts with one plain-language caption, optional timezone guidance, and a complete All grades view.
- Removed competing average and student marker lines from grade distributions, using one outlined result bar and a written session average instead.
- Added focused historical trend graphs to the dedicated TOK and Extended Essay boundary pages without adding prediction content.
- Synchronized grade-distribution tables with the chart’s May or November selection, while retaining All Sessions for broader comparisons.
- Fixed missing-boundary selections so the next-grade field says unavailable instead of incorrectly implying the top grade.
- Replaced “markband” and “candidate” jargon in result tables with clearer grade-boundary and student labels.
- Relabeled predicted-mark results as weighted score and marks to the named next grade, removing ambiguous “Grade” and “Points Away” labels.
- Added a plain-language FAQ for experimental forecasts, separating boundary uncertainty from exam-performance predictions.
- Moved the full TOK and Extended Essay core-points matrix behind an optional explanation and kept dedicated boundary pages focused on boundaries.
- Condensed the diploma sidebar to total points and diploma status, with subject and core grades available in an optional breakdown.
- Removed the duplicate forecast card from subject pages and placed the chart and model checks behind the forecast summary’s optional details.
- Removed false decimal precision from student comparisons and labeled every ranking as approximate.
- Aligned the calculator, FAQ, assistant, and results guide around plain-language grade outlooks while keeping technical statistics optional.
- Prevented saved assessment marks from exceeding a newly selected component’s maximum and producing impossible scores.
- Focused historical charts on the student’s current predicted-grade boundary by default, with all-grade comparison optional and simpler minimum-score wording.
- Reduced grade strategy to one recommended action and one plain-language outlook, with assessment calculations and historical comparisons in a single optional section.
- Removed the inferred bell curve from grade distributions, surfaced the student result and session average, and placed chart guidance behind one optional explanation.
- Made collapsed subject cards keep only the weighted score and predicted grade while hiding boundaries, insights, assessment controls, and analysis links.
- Reframed forecast likelihoods around a fixed student score, hid model diagnostics behind an optional section, and made assistant trend answers less speculative.
- Moved session, timezone, syllabus, and pandemic-era reference notes behind one optional disclosure and added a dedicated selection guide.
- Simplified forecast and distribution language, removed repeated chart descriptions, and moved student-count caveats behind an optional explanation.
- Simplified statistical summaries, hid advanced boundary statistics by default, and added a plain-language results guide.
- Condensed collapsed subject cards to the subject name, weighted score, and awarded grade.
- Eliminated the Extended Essay refresh flash by aligning server-rendered and hydrated calculator state.
- Added hover and keyboard tooltips for truncated assessment names in the main calculator.
- Aligned EE and TOK grade distributions with the graph and always-visible table used by standard subject pages.
- Added official Extended Essay subject-group and TOK grade comparisons for six examination sessions.
- Refined the Extended Essay calculator and rebuilt its boundary history and core-points matrix for desktop and mobile.
- Added session-level diploma benchmarks and an estimated overall-score percentile to the main calculator.
- Added grade strategy tools with next-grade recommendations, assessment impact, historical confidence, and session-by-session what-if results.
- Brought compact next-grade strategy, confidence, percentile, assessment impact, and historical what-if insights into the main calculator.
- Added final May 2023 results for 164 subject and level combinations and November 2023 results for 100.
- Added final November 2024 and November 2025 results for 102 subject and level combinations each.
- Added May 2025 candidate totals, mean grades, and grade distributions for 160 subjects.
- Expanded the exam-session switcher so students can compare November and May sessions.
- Marked the May 2025 figures as provisional to match the source bulletin.
- Redesigned the assistant as a modern AI workspace with image uploads, tool activity, and automatic subject-mark entry.
- Added inline subject boundaries, grade margins, and a compact diploma summary to the main calculator.
- Introduced experimental November 2026 boundary forecasts with prediction intervals, rolling backtests, and personalized grade probabilities.
