There is no such thing as “zero percent chance” of “dropping out” after a Bachelors.
It’s not a race. Many people graduate with a Bachelors, get a job, do well, and head off to grad school with a renewed focus (or better focus) on what they want to accomplish in grad school. You don’t “drop out” if you finish your degree and then head out to get actual, real life experience before getting more training or sharpening your skills.
I work in corporate recruiting- I’ve met thousands (no joke) of people who regret the Master’s degree they did and would love a “do-over” except time, money, etc. (i.e. real life) intervene.
Pick the right college for you right now. You have a decade plus to worry about grad school.
