Should I repeat another year of HS in order to attend IB?

[Depressedfridge]

I'm currently a Grade 12 High School student in the Czech Republic, and the Czech Upper Secondary School system usually lasts 4 years (graduation - Grade 13).

Right now, I have 2 options: I could move to Canada and graduate in Canada (the academic year 2023/2024.) Or the second option is to repeat another year of high school and attend the IB programme in Denmark.

I plan to study for a bachelor's degree at top universities in the EU, e.g., the Netherlands (UoA, Utrecht University, Erasmus University of Rotterdam...) or Denmark (Copenhagen Business School, Aarhus University...)

I just don't know whether I should add an extra year of HS because I feel I will be behind my current classmates.... However, completing the IB will give me an advantage in admissions at unis. Please help me and provide me with advice Thank you very much!

PS: I was already accepted to all schools in Canada and Denmark.
