Ancient History!!

Going through some old stuff I stumbled on this piece of old paper...I have no idea why I kept it all these days...or should i say years!!...

I remember that I used to love math n' physics but after a whole year in collage I realized that there's nothing real about real analysis...mechanics was kinda nice though!! Either ways I failed n' looking at this piece of paper am not so sure what they meant by the piece of information circled in red!!!!

I had a good laugh out of this :)
