No, melodic minor is something else. It changes going up and coming down. It goes like:
Scaleing up: 1-2-b3-4-5-b6-b7-8
and going back down : 8-7-6-5-4-b3-2-1
So the guy before me has it right for going down the scale, but going up it it's just natural minor, it's a really weird scale, I never use it.
