At our company they still hire based on who you are and not what you rating you have. Having the rating and not being the rights stuff from a company perspective is an expensive exercise... We are NEVER interested in the rating if you dont have the hours, specially not for contractors. If you have the hours we are always willing to look at training the right person for the rating...
In other words take the advice giving by a lot of people here: get a job first and then look at sorting the rating... You are planning on playing Russian Roulette my friend
