Start of the qual­i­fy­ing round

Here is the qual­i­fy­ing (remote) round of the com­pet­i­tion. You can solve prob­lems until Novem­ber 12, 2019 inclusively.

Please remem­ber that your solu­tion of every prob­lem should include not only the right answer but the full reas­on­ing as well.

We will be happy if your friends who like math­em­at­ics also par­ti­cip­ate. How­ever, every assign­ment should be done indi­vidu­ally; oth­er­wise, your sub­mis­sion will not be considered.

You can write your solu­tions by hand and scan them or type them using a text edit­or. Solu­tions should be writ­ten in Eng­lish, Esper­anto, French, Geor­gi­an, Ger­man, Kaza­kh, Per­sian, Romani­an, Rus­si­an, Span­ish, Thai, Turk­ish, Ukrain­i­an or Uzbek. Use of oth­er lan­guages should be agreed with the organ­izers in advance.

You do not need to repeat the text of the prob­lems in your paper; please write down your solu­tions only.  For anonym­ous grad­ing, you should not write your name on the paper sheets with solutions.

The win­ners of Olympi­ad 2018/19 (those with Dip­lo­mas I‑III) can par­ti­cip­ate dir­ectly in the final round.


How to sub­mit solutions

The solu­tions should be sub­mit­ted to the Jury by Novem­ber 12 using this online form:

You can upload both text files (in TXT, DOC, DOCX or PDF formats) and scans of paper works (in JPG and PNG formats). The total num­ber of files should not exceed 10. The files with the solu­tions of the prob­lems should not con­tain the sur­name, name and oth­er per­son­al data of the participant!

Nota Bene! It is not allowed to use the same regis­tra­tion data for send­ing works of sev­er­al par­ti­cipants. If you are a teach­er and want to send papers of sev­er­al stu­dents, please write about this to the organ­iz­ing Com­mit­tee, and we will offer a con­veni­ent way to do it.

Any ques­tions?

You can send your ques­tions (but not the solu­tions of prob­lems) to the organ­izers to olimp@​formulo.​org.
