How many kids from your school are typically accepted from your high school? Your class rank is important in that context. If, say, 50 students are accepted each year (the number doesn’t change wildly, it remains in a certain range), and your rank is in the top 30, you’re probably safe. Outside that, it’s anyone’s guess. There’s no such thing as a “shoo-in”, your numbers are what they are, just write a kickers essay- Good Luck!
