Should I buy the Powerscore LSAT bibles if I already took the PS cl?

I finished taking the Powerscore LSAT cl and consequently have all of the lesson books and I also have access to the Powerscore online student center. In addition, should I also buy the PS Logic Games and/or Logical Reasoning bibles? Would it be worth it? Or is most of the material going to be in my lesson books that I already have? (i don't mind spending the extra money, as long as it will be well worth it)
