Drywall is usually cut by using a utility knife I usually cut the face side first to give me a sharp edge. If you cut the back edge which is the brown side you end up with a jagged break Mark on the face side (the good side)
to cut the drywall panel across the width measure and mark the locations then place the drywall T-square onto the panel and score the panel with a utility knife deep enough to penetrate the paper right through. Then support the drywall from one side holding it firmly and bend the other half backwards.
