"I tried my Best".....

When I say "Best" I was not referring to the small village in Netherlands. I was actually referring the word "Best".
Why did I come up with that suddenly ? What is the relevance, I'm pretty sure everyone in this world (well it should most of the people in the world) knows the meaning of the word "Best".
OK without further due, the reason I bought it up is, I sat for two of my final year papers today. Last paper I had today was "Software Engineering Methods and Management"... All I can say about it is "I tried my Best"...
So is that mean I really did enough to get an A+ ???
When you are considering my scenario, I say there are 3 different definitions for "Best"...

1. I studied really hard and I'm really good at Software Engineering. So based on that, you can say "I tried my Best". (This is a sure A+)
2. I studied OK and I'm OK with Software Engineering. So based on this, you can say "I tried my Best". (This is somewhere around B)
3. I studied a little and I really suck at Software Engineering.So based on this, you can say "I tried my Best" too. ( This has a fine line between Pass and Fail. Marker is the only person who can decide which side you'll be end up at the end of the day)

So I guess you'll see there's a certain weight attach to the word "Best". That weight is the thing that gives the word a real meaning and a real value. So without that added weight the word "Best" is just another word in the vocabulary.
So next time When someone says to you "Machan I really tried my Best".... Stop for a while and think what did your "Machan" really mean out of the above 3....

(and for all of the curious kind out there, I meant the third one ... Well to be honest I'm not much of a Software Engineer and I'm much of a S........... )
