Just be aware that there are some errors on the 2009, but there is a thread on here that tells what the errors are. The 2009 is a good predictor, but it doesn't guarantee anything. You can read up on some posts on SDN. The stories range from getting like 25s on the 2009 but lesser scores on the actual and then getting 16s and 17s on the 2009 but getting 20s on the actual. If you score well on it that's great, but stay hungry because it isn't the real test; if you don't score so hot, then just keep grinding and reviewing everything leading up to the exam. Usually, from what I have read, most people take the 2009 as their last test a couple days or so before your actual exam.
