I don't really know how to start this off. I'll just go into what I want to say. This isn't good. This isn't close to good. I don't want to be an ass or anything but when you say you sucked a bit thats quite off the mark.
You see the Comp score? Thats your composite score or how you did on the whole test. The second number, the 4, thats your percentile. That means that you did better than 4 percent of all the people who took that June PCAT. That means 96% of everyone who took the PCAT in June did better than you.
Many schools have a minimum PCAT percentile score of 50. I don't know if LECOM does or not but you're going to need to do better. However, the problem with is Pearson will automatically cancel your score if you jump more than 50 points in your percentile. So even if you can bring up your score you are going to have to fight with Pearson on whether your score is valid or not.
Not only that but it seems that you want to apply this year. That means you have the October PCAT and maybe the January PCAT to improve your scores. Thats only a few months to learn a lot of material that you obviously don't know. Again it might seem that I'm being mean but you need to wake up.
DON'T apply this year. I'm pretty sure that you would not be able to get your score over 20 if you tried this October. There's obviously some basic information that you don't know yet. You need to improve in every subject and I'm not even sure you could learn it all by next year. But applying this year would be a waste of money. You need to shape up and, I don't say this to many people, rethink what you are going to do with your life because pharmacy may not be for you.
Edit: found this thread so you can analyze your score yourself

Edit 2: looked up LECOM's statistics. they don't have a minimum PCAT requirement but the average composite score for last years accepted students was 73. You have a 4.

I'll say it one more time, sorry for being an ass but I think you need to hear it.
