If you have a close relative, such as your Mom or Dad, grandparent, brother or sister, who has graduated from a specific university, then that university may consider you to be a strong candidate for admission to that school.
Many colleges give a family discount (not in dollars, but in admissions acceptance percentage) to applicants from the same family.
In almost all cases, you still have to be a solid candidate.
Your grades and test scores need to be respectable. But your legacy status could very well push you over the top.
In some instances, legacy candidates are 20% to 50% more likely to get an acceptance letter than a non-legacy would.
Okay, so this isn’t something you can really control.
Even though you can’t control it, it’s something to consider when you are making your college plans.
