In your render settings under Sampling, is the integrator set to Path Tracing or Branched Path Tracing?

It was set to Path Tracing. I tried changing this setting and rendered the result before and after. Before with Path Tracing https://www.dropbox.com/s/s6587m89xdrgv5w/Screen%20Shot%202015-07-23%20at%2020.03.42.png?dl=0 After wtih Branched Path Tracing https://www.dropbox.com/s/5chlyjviniud2pa/Screen%20Shot%202015-07-23%20at%2020.02.08.png?dl=0

In the starter file the area lamps need to be set to multiple importance. I'm brushing up on my basics, and was puzzled why a simple glossy shader was producing so much noise.
