Can I Even Trust The Level System?

What do you think would happen between you and your classmates if you were transported to another world? Being told that you are needed to save the kingdom from destruction from monsters working together to stage a war. How are you supposed to react to that call to arms and being given a system to level up and asses your powers? To rise and fall and the safety of not only the kingdom but your classmates. Wouldn't that make for an interesting first year in college.
