Web delepover job , test , certification

I am a web developer, i know

• html+5


• css+3


• JavaScript jquery


• php and mysql (still learning. But, will be completed in about 1 1/2 months)


• asp.net(after php)

I don't have much experience at now. But, i'm only 15 years old.

Is there any certification test, campus, small job that i can do to increase my experience level.
