The Mega-Talent Talent Development Center is holding All-Russian Online Biology Olympiads. We believe that every student is talented and we offer tasks that reveal hidden abilities. We reward all participants and after each Olympiad we give certificates and thanks to teachers free of charge.

Some statistics about our work:

MDG "Mega-Talent" has organized more than 400 Internet Olympiads in 47 school disciplines.
9,000 schoolchildren and students from 12 countries have already become participants in Biology Olympiads.
We are compensating organizational expenses and have already paid teachers 2,500,000 rubles.
98% of teachers are satisfied with the results of participation in the Olympiads and become permanent organizers of the Mega-Talent Olympiads.

5 steps to meet the teacher

We want it to be easy and pleasant for you to work with us. To do this, we follow 5 steps, designed with the teacher in mind:

We open access to tasks for all classes and provide guidelines for the Olympiad.
We give each teacher a certificate and gratitude. Every season we update the design of award materials so that your portfolio is meaningful and bright.
We return money for printing assignments, awards and other organizational expenses.
Every month we reward the most active organizers of the Olympiads.
We advise on any issues related to distance Olympiads.

The Mega-Talent Olympiads are like ordinary Olympiads, only better!

The Mega-Talent Olympiads are held remotely. You choose the time and place of the event. In a familiar environment, students feel more confident, which means they fully concentrate on solving problems.

Students with different levels of academic performance participate in our Olympiads, because the tasks of the Mega-Talent Olympiads are based on the school curriculum and comply with the Federal State Educational Standard. Assignments help to assess the level of knowledge and encourage students to develop logical and analytical thinking.

Sets of tasks for each class consist of 15 test questions of different types:

Questions with one or more correct answers.
Questions on the analytical and chronological sequence.
Exclusion questions and correlation of two data series.
Test tasks for working with illustrative sources.
Test tasks for solving problems.

How much does participation in the All-Russian Biology Olympiad cost?

For each Olympiad, we set the minimum possible cost of participation. In addition, up to 30% of the registration fee of each participant is returned to the teacher: for the printing of assignments prepared by us, diplomas, certificates and other organizational expenses, you pay the remaining amount to us (you can find out the exact amount after registration).

Each teacher-organizer participates inteacher rankings . By holding more Olympiads, you increase your chances of getting really valuable and necessary prizes. Every month MDG "Mega-Talent" rewards the most active teachers. The work of each teacher is invaluable, and we are glad to cooperate with specialists from Russia, as well as neighboring countries.

How often do we hold biology olympiads?

Whenever you decide to hold an Olympiad, one of our main educational events will most likely take place during this period. In total, there are three seasons of the All-Russian Olympiads in Biology (winter, spring and autumn) and four seasons of international Olympiads per year. For each season we prepare new tasks. This allows you to participate several times a year.

How do we calculate results?

All tasks are checked automatically. This allows you to achieve objectivity in the evaluation of results. The computer calculates the result and publishes it on the website. After that, the organizer can download, print and present awards to their students.

How to organize a Biology Olympiad for your students?

Everything is very simple:

you register on the website and pays for participation in the Biology Olympiad for their students (this must be done before the deadline for accepting applications);
after the start of the event, files with tasks will become available in your personal account on the site.
by printing them out, you can already proceed directly to the Olympiad in Biology (for each participant, you need to print a separate set of tasks);
you fill in the answers of each of the participants online in your personal account;
after checking the tasks by the system and our methodologists, the results are immediately published on our website;
all award materials will become available for download in your personal account.

How to pay for participation in the All-Russian Internet Biology Olympiad?

You can pay for participation in the Olympiad using:

bank card (online);
receipts at the Russian Post office;
electronic payment systems (online).

Can pupils and students from other countries participate in the event?

MDG "Mega-Talent" organizes educational events at the international level. All students are eligible to participate, regardless of their nationality or country of residence. However, in order to understand the essence of the tasks, students must be fluent in Russian.
