LEO stands for Learning Environment Online.
And I didn't know it till now, like after almost one and a half year in RP. I don't know it's mine or RP's fault. I mean, when we first step into the school, nobody explains what LEO stands for! I think maybe the facilitator don't even know! All we know is LEO is the place where we do our rj and stuff, yada yada... And that's all.

So I guess no one know it huh? Well, now you do! :]
