Thanks a lot!
Yes, you are right, it wasn't a formal defense. Here in Suriname at our only university BSc research is sometimes close to masters level in terms of complexity which makes it feel like a defense. This is because of remnants in the curriculum from the transition from the old system where you got the title of drs. (doctorandus) which was split up into the modern BaMa system.

I changed it to "present" in the post to avoid further confusion. 😅
