classes usually begin in early or late august depending on the school. the application/ interview process begins in fall (after labor day). It is best to interview earlir in the year as one has the "best"chance of seeing all the school before their classes fill up
So one would want to do some take the pre req courses, shadowing, take the mcat, and get your app turned in as early in the fall as possible the year before you would like to matriculate. Then that fall, winter and spring you would want to interivew at the schools of your choice and weigh your decision on which one best fits you as a person.
Some schools will accept you on a conditional basis without your mcat score, but will require it for you to start classes. Also some schools will take your application all the way into late june.
For specific requirements, you should contact the schools
