Removing wallpaper is one of the most tedious home improvement tasks. Just remember to be patient and plan on spending way more time one your wallpaper stripping project than you thought is would take. Also be careful with the scoring tool. You will probably get frustrated and begin to push harder on the scoring tool, which in turn will leave permanent marks on the drywall beneath the wallpaper. The correct way to score is a less pressure, more passes with the scoring tool. Once you start to peal the wallpaper off the wall (you've steamed it and it just peals off by pulling on it) don't get too far ahead of yourself. Make sure you steam the whole piece of wallpaper or you risk pealing off the paper on the drywall and that's more work to fix.
