Instructions for students
- White paper is the official paper on which you have to write your solution. Make sure you fill your country code and university code, the problem number on each page and the numbering of the pages for each problem separately. Answer can only be written on the front side of the white page.
- At the end you have to put the solution for each problem in a separate envelope corresponding to the problem number. You also have to write the number of pages included in the envelope on the space provided outside the envelope.
- Green paper is only used for scratch work and you have to leave it on your desk after you finish.
- Blue paper is to write your questions during the first 30 minutes of the contest. These pages are to be left on your desk after you finish.
To the left of your table there are 4 cards (white, blue, green, yellow), which serve for certain needs that you will have during the Olympiad. For each request, it is enough to raise your hand with the corresponding card.
- White card ─ when you need paper [official paper (white paper) or scratch paper (green paper)]
- Green card ─ when you need to use the toilet
- Blue card ─ when you need water
- Yellow card ─ when you have other questions not related to the test
