How should one prepare for the MCAT?
The most important things are (1) to take practice MCAT exams, available for free from the MCAT website; and (2) to thoroughly study the subject matter covered on the exam. MCAT prep courses are offered by several companies (such as Kaplan and Princeton Review.) Some students find that these courses help them to be disciplined about their studying and provide helpful additional practice. Whether or not you take a prep course, you need to make your MCAT preparation a top priority. The best preparation is practice, practice, practice. You should familiarize yourself with the style of questions, set aside several hours to take timed practice tests, and make sure you understand any errors you make in the practice exams.
