Well, each grading system is different. But is getting 50/100 the *only* condition to pass the course?

Well, let's say the course also required you to finish all labwork (since I study physics, that is one example that comes to my mind)

If I passed the course, it follows that I got a grade higher than 50/100. If I got a grade higher than 50/100, it doesn't necessarily follow that I passed the course.
