My oppinion is that the writers dont really have this capacity of making Courtney's advantages help her a lot. I know many people will disagree, but how many goofs do we see around there, they cant even pay attencion in some important details.
Like in last episode, Owen said he blamed his little brother for doing something, but he doesnt have a little brother, he has two brothers that are older than him. In the same episode, Bridgette said that Heather was the only person who ate an cockroach, but Leshawna already ate a lot of them in Brunch of Disgustigness.
In episode Super Hero-Id Leshawna is eating some cheese with Lindsay and Beth, but in episode One Flu Over the Cuckoos, she said she was lactose intolerant.
Okay..these are just details..but it proves that the writters dont pay attencion in many details. I know that Courtney's advantages were really important in episode's 14 plot. But now, most dont really pay attencion to it. Chris dont mention it more, Courtney always tries to call her lawyers, but her lawyers never do nothing, they almost never help her. Yes..they brought her back to the game, and yes they gave her some advantages. But at this point, no one, ALMOST, never complained about that, only in episode 14. So...to finish everything i said..my oppinion of this is..that Courtney has many advantages and that they would help her doing the challenges, but that they dont because the writters dont foccus her plot in that.
