I don't know, I think it's mostly irregular. Even with feminine and masculine it's mostly irregular; it mostly it ends up with и though. Neuter are significantly less often than feminine and masculine. Here is what I'm talking about (here you have no any neuter nouns) - http://mylanguages.org/ukrainian_plural.php
I'm confused about the word "ми", doesn't it mean "my", "mine"? If so, what's the diference between, "my student" and "my students"?
студент - a (male/female) student (plural: студенти)
студентка - a female student (plural: студентки)
What is its a mix of both male and female students? Does it matter which one you use
