I am practicing math at the moment and I have a tendency of re-writting the whole entire equation down when I solve. Is this normal and wise? or is it just plain stupid?

I would say it depends. Are you periodically running out of time? Do you lose accuracy when you don't? Personally when I do, I jot stuff down all over the place (after all, it's dry erase!) and go problem by problem. If it's a problem I've marked, I leave my scratch work and come back to it (I'll usually still remember what I was thinking once I got back to it). I save writing wherever I can but I write #'s in intermediate steps if I have one to avoid making mistakes. I can't say that I had a lot of left over time at the end but I didn't run out of time either.
