Panic, should I?

1st situation:
Just finished the exam, sat and ate in the mensa with Kobua and Kom (as usual..).
Suddenly Kobua said something.
“Why I never saw you panic, Jul?”
Me: “What? I don’t get it”
K: “Ya.. before the exam..during the exam.. before presentation.. you just look like this *show with her face how I looked*
Me: “really? like that?”
K: “Yes.. you look calm.. just smile.. speak little.. it’s like nothing will bother you..
Me: “really? *once again - still don't believe - did I look like that?*
K: “Ya.. While me.. well, you know I’m always panic..
and you know what happened when I’m panic..”
*HUAHAHAHA.. yes surely.. I won’t forget that day… one day full of SHITS.. hahaha.. *
Me: “hehehe..”

2nd Situation:
5 minutes before the exam end.
I just realize I still have a lot of questions to be answered..
So I choose questions that can be answered without too much thinking, leave some answers blank.
And when the prof asks to stop writing, I just stop writing without eagerness to write something else..while others still keep trying to write something.. (don’t know what they write.. )
That’s it.
Finish and submit it.
I don’t feel so much worry about the answers and about the result.

Conclusion:
Should I have this ‘panic’ feeling?
I don’t know why, I rarely have it now.. or actually I never have it?
I just remember, 8 years ago someone wrote in my birthday card complaining about this behaviour (how often I did many things that made him panic while I myself never looked panic.. :p)
So.. it’s already there for a long long time ago I guess.. hehehe…
