Kaplan focuses mainly on strategies for Verbal and RC, not so much for Bio, Chem, and Math. Personally, I loved the Kaplan course. I like being in a classroom setting and learn best that way. Kaplan does go through the basics of Bio, Chem, and Math but you have to read through and study the chapters on your own time. You also have online quizzes to take that are scored and have access to Kaplan's section tests. You can go to any of the Kaplan test centers and take Bio, Chem, Verbal, and Math section tests. These are basically just pages of questions. I found this to be particularly helpful, as I was able to go though tons of questions and practice under time constraints. One of the best parts of the class is the workbook that they give you. The workbook is what you go through during classtime. I think the Orgo section in it is great (something that is lacking in the main Kaplan review book). It also provides you with a lot of little tips for remembering certain pathways and whatnot. There are also a lot of practice questions/quizzes in the workbook (way more than in the main book), as well as full length RC passages. Between the main Kaplan review book, the workbook, the online homework assignments and quizzes, and the two full-length exams you take, Kaplan prepares you well for the PCAT. If you like structure and need a guided plan to follow while studying for the PCAT, I think you will like the classroom Kaplan course.
I will also add that I had a great teacher. She was really easy to talk to and would stay after class to go over things with me if I asked her to. She also explained things really well and made complex topics (like some Orgo reactions and stuff) very easy to understand. I do believe that the instructor can positively or negatively influence your experience. Many people felt as though they didn't get much out of the class. I, however, really liked it. Studying for this exam was very overwhelming to me and Kaplan provided me with an organized, structured study plan.
