The examination is looming...,

[Silverobama]

My cousin was still playing computer games when she was supposed to study for her mid-term exams (math, English, physics, 10 in total). I said to her:

The examination is looming. Why don't you have a sense of crisis?

Is my sentence natural?

The exam is around the corner. Don't you have any sense of urgency?

The first sentence is natural enough, if you're intentionally trying to dramatize it.

For the second one, try something like "Why aren't you panicking/stressing out/freaking out/worried about it?"
