Only 1 in 7 competitors (15.3%) walked away with Gold. The 84.2% medal rate was generous by IBO standards, but the gaps between tiers were razor-thin.


Medal Cutoffs

Final score range needed to earn each award

Razor-thin margins

The Gold cutoff (130.07) sat just 0.53 points above the best Silver score (129.54). The Silver-Bronze gap was similarly tight at 0.54 points. At this level, a single extra mark on one practical station would have changed medal colors.

Hardest to score on

Bioinformatics had the lowest attainment rate of any station: competitors captured just 44.5% of its 100 available points. The station also had the second-highest correlation with final rank (r = 0.70).


Theory was king

Theory total (Papers A + B combined) correlated at r = 0.94 with final score, making it by far the single strongest predictor. Theory A averaged 63.1% attainment, Theory B averaged 61.3%.

Perfect teams

China, the United States, and Chinese Taipei are the only delegations where all 4 members won Gold. Vietnam came closest to joining them: 3 Gold and 1 Silver, with their Silver medalist finishing 17th overall.


Theory vs. Practical

Reading this

Vietnam and China topped the overall medal table, and both built their edge disproportionately on the theory exam. Saudi Arabia and the Philippines showed the reverse: their teams outperformed their theory scores in the lab, suggesting strong practical training programs despite lower theory throughput.


Curiosities

4 things the official result does not say out loud

01
r = 0.94

Theory total correlated at 0.94 with final score. No single practical station came close (the highest was Molecular Biology at 0.71). If you had to predict someone's final rank from one number, their combined theory score would be right 94% of the way there.

02
0.53 points

The gap between the last Gold and the first Silver was 0.53 points. In a 165-point competition, that is 0.3% of the winner's score. A single extra True/False statement on either theory paper would have flipped the result.

03
Biochemistry was the "easy" lab

With 67.7% average attainment, Biochemistry was the most accessible practical station by a wide margin. Bioinformatics (44.5%) was the hardest. The 23-percentage-point gap between the easiest and hardest station is one of the largest in recent IBO history.

04
Pengbo Li: +2.10 theory-practical gap

China's #2 finisher (overall rank 2, final score 160.11) had the single largest theory-over-practical gap of any competitor. His theory T-score was 2.10 standard deviations above his own practical average, yet he still finished second overall. Pure theory dominance at the very top of the field.


For 2025 Hopefuls

What the data says to train next

1

Theory decides more than any single lab

Theory alone correlates r = 0.94 with final score. Master your written exam first. Every other component trails behind.

2

Bioinformatics was the differentiator

At 44.5% average attainment, most competitors struggled with the Bioinformatics station. Spending targeted time on sequence analysis, phylogenetic tools, and computational biology gives you the most room to gain points where others lose them.

3

Just short of a medal? Here is the fix

Merit to Bronze: The gap was just 0.30 points. A steadier finish across all four labs, not one breakthrough topic, is usually what closes that gap.

Bronze to Silver: 0.54 points. Hunt for lost partial-credit marks on the theory paper before you hunt for new topics.

4

Build a full team, not one star

Every Gold-sweep delegation (China, USA, Chinese Taipei) medaled with all 4 members. Depth wins team results.
