Grad school, short for graduate school, is an advanced educational institution where students pursue specialized degrees after completing their undergraduate studies. Programs typically focus on specific fields, such as business, education, or science, and can lead to degrees like a master's or Ph.D.. Attending grad school often involves rigorous coursework, research projects, and sometimes internships. Students may also have opportunities to work closely with professors and engage in networking with professionals in their field, which can enhance their career prospects and academic knowledge.
