Many students are confused about what constitutes a safety. There is a big difference between a true safety where your grades and test scores flat-out guarantee admission and where the formal aid policy (and/or cheap price) flat-out guarantee affordability, and relatively a safe option where you can have a reasonable expectation of admission.
No formal statement of which grades and test scores guarantee admission, but no student like you who applied from your own high school in the past five years was every rejected? That one would be pretty safe. But please don’t count on it being absolutely safe. The year you apply could be the year that admissions gets tougher.
