Can you become an aerospace engineer even if your high school grades sucked and your SATs were only slightly above average?

However, it certainly is not impossible, and there are often options to study at a community college for a few years to improve your academic standing if you are not able to get into a chosen college with your high school record. The question should be, is aerospace engineering what you really want to do? If so you can speak with a guidance counselor about your options and chart a path that will work for you. Good luck!
