An "underachiever" is a person who performs below their potential or capabilities, often in academic or professional settings. This term is commonly used to describe students who do not achieve grades that reflect their intelligence or abilities. Underachievers may struggle with motivation, self-esteem, or external pressures, which can hinder their performance. Underachievement can occur for various reasons, including lack of interest in the subject matter, poor study habits, or personal challenges. It is important to identify the underlying causes to help individuals reach their full potential. Support from educators, parents, and peers can play a crucial role in addressing these issues and fostering improvement.
