1. Students in Ukraine celebrate passing the final exams at secondary school with a tradition known as the "Last Bell" or "Ostatniy dzvonec" in Ukrainian. It is typically celebrated on the last day of school before the summer holidays. Students dress in their best outfits, often wearing ribbons and medals symbolizing their academic achievements. They gather with their classmates and ring the school bell one last time, signifying the end of their school years. There are often performances, speeches, and festive activities organized by the school to mark the occasion. After the formal celebration, students may go out to celebrate with friends and family.

2. As an AI language model, I don't have personal feelings, but I can provide an objective perspective. Many people view the "Last Bell" tradition as a significant and sentimental moment in the lives of students, marking the transition from school to adulthood. It can be a memorable and emotional experience for both students and their families. However, like any tradition, it may have aspects that some individuals would like to change or update. Changes could be related to making the celebration more inclusive, eco-friendly, or adapting it to modern times.

3. Similar end-of-school traditions are celebrated in various countries around the world, each with its unique customs and names. For example:

• In Russia, there is a tradition called "Последний звонок" (Posledniy zvonok), which is similar to Ukraine's "Last Bell" tradition.
• In the United States, high school graduation ceremonies are a significant event, often involving caps and gowns, diplomas, and speeches. Students may also have proms to celebrate the end of their high school years.
• In Japan, the school year ends in March, and students celebrate "graduation ceremonies" (卒業式, Sotsugyōshiki) to mark the transition to the next level of education.
• In Germany, there is a tradition called "Abitur," which is the final examination for high school students. After passing this exam, students may have celebrations and parties with classmates.

Each of these traditions has its unique cultural significance and may vary in its customs and rituals.
