Proceed through the level as usual until you reach the part where the Agents drop out of the buildings and put you through a wooden floor. Instead of walking or jumping it, do a long Matrix jump over the gap next to it. If you make it the leap, follow the outer boards and do a big jump at the end to the windows. Once in the building, exit at the far window and you will be near the end of the level. By doing this, you will eliminate about 75% of the level.
