To return the favor, I'll agree with arcane on this one.
Going through different systems has its place, but it's at the end of your studies, not the beginning. At the beginning, you should be sticking with one approach so that you can understand the test and get a handle on the logic. You generally go through a few stages (these are going to take longer than a few days to go through, for most of them):
1) I have no idea what's going on
2) OK, I see what's going on, but I have no idea on how to approach this question
3) OK, this book has given me an approach, and it leads to me getting correct answers, but I don't really understand why
4) Oh! That's why the method works - these shortcuts are just exploiting common logical issues. But why didn't it work here?
5) Ah, ok, now I see it - the method breaks down in certain questions when X happens. Tricky, LSAT. Tricky.
At that point, you have the logic of the test down, and you can understand how the method walks through that logic. Now, you're not just applying the method - you're using the method as a skeleton to guide you through an intellectual understanding of the material. It's at this point that you should incorporate another method, because if you can then explain how two different methods arrive at the same result, you've Neo'ed the Matrix and are seeing behind the scenes.
