This has been covered many times before.
If a school says that they screen, it really doesn't mean what you think it does. All they do, if they do screen, is to look at your state of residence and then apply somewhat low cutoff values to your GPA and MCAT scores accordingly (so getting a secondary doesn't mean you are within the limits of people that they generally accept). They don't have the time at this stage to read your personal statement, look at your "upward trend" in grades, nor review your listed activities in AMCAS as they get thousands of applications. They may just want you to send in money as a way of self-selecting.
Basically, don't rely on any medical school pre-secondary screening to make the decision process for you. They'll all probably send you a secondary unless your stats are lopsided or low.
