A true safety is a place
- where you are guaranteed admissions for your stats,
- that you can absolutely afford without any aid other than guaranteed federal aid (as determined by the FAFSA) and/or guaranteed state aid and/or aid guaranteed for your stats by the college/university itself,
- that offers your probable major(s),
and - you are happy to attend if all else goes wrong in the admission and financial aid process.
Have you identified a place like that yet? Provided you like your safety, everything else is just gravy. Find at least one safety, and then build your list up from that base.
