How does the scoring work?

I cannot work out how the scoring works in game... Information is hard to come by, does anyone know what activities award points, and how much?

The points are distributed as follows:

• 2 points for a bomb plant. (Terrorist Only)
• 2 points if that bomb explodes. (Terrorist Only)
• 2 points for a kill.
• 1 point for an assist.
• 4 points for defusing a bomb. (Counter-Terrorist Only)
• 2 points for rescuing a hostage. (Counter-Terrorist Only)
• -1 point for killing a teammate.
• -1 point for committing suicide.

2 points for a bomb plant. (Terrorist Only)

2 points if that bomb explodes. (Terrorist Only)
