The PCAT is tricky to score via any ballpark, because from my understanding, it is based on how many questions you get right and compared against the national average of everyone who took that exact same test with you. If you take the PCAT in July (like I did), it is based on the scores from the last year. Kaplan had a free online PCAT that you could take and it gave you a general score, but it isn't really all that useful, except to show you a random score against a few other people and then see what are your stronger and weaker areas.
On that note, try and make sure you master areas and study well what you think you all ready know. If you score super high on certain PCAT segments, your average shoots up and it can save you from needing to retake it if you have a bad day in one section.
