My first practice test was a 169 and I scored a 174.
If you are a person who finishes all the questions in the LR sections and just need polishing, I strongly suggest doing the sections backwards. That way your mind is fresh for the hard ending questions, and the crunch time is less stressful b/c you are just flying through the easy beginning questions. I think doing this jumped my score up about two points.
As a caveat, I would not suggest doing this if you do not regularly finish the LR sections. It could bog you down at the end and lower your score.
