Here was my study program with Dr. Collins... got a 91 composite (I did this while taking one class in the summer with no job, so adjust your schedule accordingly)
1. Made a study schedule
-Exam date was July 18th, began studying June 1st
-Each week was dedicated towards each section of the PCAT (I did chem, then quantitative, bio, verbal, reading)
-I made room around times I knew I wouldn't study (July 4th, my birthday, etc.)
-Took AT LEAST two tests per day TIMED (tests meaning 1 chemistry section and then 1 quantitative, for example) I would do 4 or 5 at most.
-The week before the PCAT, I took one full-length practice test/day
-Followed my schedule LOOSELY... didn't want to get burned out
2. Review, Review, Review Practice Exams
-Identify any answers you "guessed" on... don't lie to yourself even if you guessed it right
-Immediately look over the incorrect answers and figure out WHY they are correct
-Once you've found your weakness, write them down... and study them frequently
3. Bought Pearson's Practice Exams Online
-Pretty expensive but worth it in my opinion
-Took these exams before my PCAT exam to get a feel for an online test experience (you'd be surprised how different it is to read off a computer than a piece of paper)
-Whats cool about these Practice Exams is that they give you a range in which you will score in the actual PCAT (pretty helpful to improve your score)
4. Tried to read whenever I could (I was expected to get a 10-25% in reading based off of Pearson, I read as much as I could to help my score.. got a 47% in reading which I was most happy about)
-Reading books before bed
-Got on yahoo and read interesting news articles
5. Stayed Healthy
-Good nights sleep
-Ate breakfast every morning
I didn't necessarily study "every day" but I did study more often than not. Looking back, I pretty much only studied during the week because that's just how I normally function academically. If you study better at night, do that. But once the PCAT is a week away, try to mimic a a full-length test experience no matter what. Limiting any unnecessary stresses such as test exhaustion will help you achieve your optimal score.
As for the Dr. Collins, read the Chemistry study guides and know the concepts and know the Biology tests and the concepts they cover. Got a 98 and 99 in those sections, respectively.
Good luck!
