Good Afternoon
When I was in my first years in college, some of my classmates often talk about powerful devices such as dual cores (by that time it is the hottest). they even interact with the discussion like pros on computer hardware. I let them do what they want, besides I don't care about them, what I care about is my studies.
by this time I'm not a newbie when it comes to computers, by that time I could even fix hardware errors and troubleshoot computers, not to mention I've reformatted bunches of systems already.

When the examination day comes, I'm late (what do you expect from me, I'm always) and not yet prepared.
But I'm safe for what is still saved in my  memory. when the results arrived, I got the 2nd place for the highest scores (yey!) and those who act and talk like pros nearly failed it.

Lesson: .Talk is cheap, work your brains : )

Have a nice day!
