TASK 1

Test submission status

Upload your test predictions and check the format and acceptance status in the submission portal. Test scores and ranks remain hidden until final results are released.

TEST / 928 QUESTIONS

Submit and check your file

Enter your Team Name and Contact Email, then upload a ZIP containing one root-level predictions.jsonl. The portal checks the public prediction format and shows whether your submission was accepted.

Open test submission

Test resubmissions: unlimited before the deadline

You may submit revised Test predictions as often as needed before 15 October 2026, 23:59 Anywhere on Earth. There is no daily or total Test submission quota. Keep the same Team Name and Contact Email for all revisions.

Your latest accepted, valid submission before the deadline replaces earlier accepted submissions for final evaluation. An invalid or rejected upload does not replace your last accepted submission. Save each acceptance receipt.

Uploading an identical previously accepted file returns its original receipt and acceptance time; it does not create a new revision or change which submission is latest. Earlier records are retained privately for the competition audit trail. Test scores and ranks remain hidden until final results.

Policy updated 16 September 2026, replacing the previous Test submission-count limits.

01 / FORMAT CHECK

Check the prediction format

Format feedback covers the ZIP, JSON structure, required fields, and public case IDs. It does not assess whether your answers are correct.

02 / ACCEPTANCE

Keep your receipt

An accepted submission returns a receipt ID and acceptance time. A format pass alone is not an acceptance receipt. Save the result shown in the portal.

03 / FINAL RESULTS

Scores remain hidden

No test score, rank, or answer-correctness feedback is shown during submission. Official evaluation follows the competition deadline.
