Hi Sara!
Yes, I do think it would help (or rather, it cannot hurt
).
The nice thing about the SuperPrep is that you get to see how the test makers think about the questions. For that reason, many people consider the SuperPrep one of the most valuable tools out there. Just reading the language they use to describe the questions and certain patterns of analysis is helpful.
The one problem with the SuperPrep is that the test makers also play "hide the ball" a lot. Instead of describing techniques for solving questions, they simply describe the error. So, their explanations can get a bit obscure at times, and that diminishes the value of the book. It's kind of like they wanted to write good explanations, but at the same time they didn't really want to give people any real secrets to figuring out the exam. It gets annoying--especially in the Logic Game section where they describe elements of the correct setup but don't actually draw it out.
Thanks!
