Olympiad Diaries
Day 5
Day 5
Participants of the Open International Biology Olympiad (OIBO 2025) tackled the theoretical round, which consisted of 60 Olympiad tasks from various sections of biology: botany, zoology, biochemistry, histology, physiology and genetics. Participants had to solve them individually. They had to undergo multiple choice tests, matching questions, and calculation tasks. Total duration of the round was 4 hours.
Ziyad Ahmed Alnemarim, a participant of the Open International Biology Olympiad from Saudi Arabia, completed the theoretical round in 3.5 hours and spent the remaining 30 minutes checking his answers.
"I found the multiple choice tests the easiest, but the calculations and matching tasks were a bit unusual. I started taking biology in high school, and I liked it much more than chemistry or physics. In Saudi Arabia, I had the opportunity to participate in the National Biology Olympiad. Due to my good results, I passed additional selection tests and training camps. As a result, I managed to join the team for the Open International Biology Olympiad, and I am very glad that I came to Sirius," Ziyad said.
In the afternoon, ‘One World, One Quiz, One Team' was held for the children, which combined questions on geography, history, culture and traditions of different countries. In the evening, our participants had an opportunity to visit the skating rink.
