lost and frustrated

DANG, I REALLY DON'T KNOW HOW TO STUDY FOR ISO!

It's SO frustrating.

Argh.

Breathe.

Breathe in, breath out.

Sigh. I need to find a way to make sure the damn data input stays in my memory. The secondary memory, not the first, since the primary memory is temporary storage and data will be lost if power is cut.

Bleah... (X_X)
