No, it's not sadomasochism (do I spell it right?). SM stands for Studying Methods.
Restu was asking me and some other friends to wrote our studying methods for her, so, yeah. It's kinda surprising me when I found out that my studying methods were actually good, but I hadn't applied it, yet.
Well, just like what Alice said, "I give myself a very good advice, but I very seldom follow it" Oh my. Btw, a bunch of homeworks still waiting for me. So... I better turn off the computer now.
