  1. its not single layer if there is metal on 2 layers

  2. But why single layer if I may ask?

  3. Good Job!!! Must have been a B.

  4. Looks like a surface mount component on the back of the board. There are a few commercial electronics designed single layer (not manufacture like this is designed – no copper in barrel or on other layer.

  5. I, too, have placed screw terminal backwards before.

  6. With commercial board design, less layers=less cost of production. Back when I was doing sch capture and PCB design, we spent days on end trying to get everything on a 1 or 2 later board if at all possible. to cut down on parasitic inductance, use zero ohm carbon resistors.
