Question Types

The contest includes a variety of question formats to test your versatility. Below is an overview of the most common formats.

Submission Attempts and Scoring

• Each MCQ, MCQ Multi-select, Sort, and True/False Set question-part allows for no more than 3 attempts. After 3 incorrect attempts, such question-parts will be disabled and score 0. No partial credit is given; an exact match is always required.

Main Problems Scoring

The following lookup table illustrates SEL's scoring scheme:

• Every 30 minutes, teams receive a free skip to discard a problem without penalty.
• If no free skips are available, skipping a question incurs a 3 point penalty.

Economania

At 10:00 AM, the Economania section unlocks, offering 15 new problems across 5 categories (Microeconomics, Firms, Game Theory, Macroeconomics, and Financial Economics). Each category has 3 problems in ascending difficulty:

• Unlock each subsequent problem by completing the earlier ones in that category.
• From 10:00 AM to 11:00 AM, completing an entire category doubles its points as a bonus.
• After 11:00 AM, participants can still access Economania questions, however bonus points shall no longer be awarded.
• Economania problems cannot be skipped.

Awards and Rankings

The school category and open category have separate leaderboards and rankings.

The awards are determined according to the cutoffs below, where n is the total number of teams, and ⌈x⌉ represents the ceiling function. Teams are ranked by the cumulative point total. A rank of r indicates that exactly r - 1 teams scored strictly more points.

The top 5% of teams will receive the Gold award, the top 15% will receive the Silver award, and the top 30% of teams will receive the Bronze award.

• Teams will be ranked according to the cumulative point total obtained during the contest.
• A rank of r denotes that r - 1 teams scored strictly more than that team.

Conduct of the Contest

Participants may sign into the official SEL Platform at 08:40 on the day of the contest. The contest will begin promptly at 09:00 and end at 13:00.

The Main Problems are accessible throughout the contest may each contain multiple question parts. Main problems have a wide spectrum of difficulties, and later problems will tend to be harder. Each team may work on up to four problems at once. Upon completing a problem, the team may select a new problem to attempt from a pool of other questions.

From 10:00 to 11:00, Economania problems will be available for teams to attempt independently and concurrently with the Main Problems. Economania problems can range from Easy, Medium, or Hard levels, and may contain special variants of question types (e.g., unique multi-step MCQs). Regular Points and Bonus Points earned from Economania problems will be added to the team’s overall score.
