Your guidance counselor should have a one or two page write up of your school that is sent to every college. On that sheet will be the GPAs of the last class or two, ranked by percentile. So top 25th percentile might be 4.0 to 3.8, second 25th percentile might be 3.79 to 3.5. See if you can estimate your percentile for your school.
If you’re not in the top percentile for your school, then these top 30 schools are very unlikely.
