Charvi Goyal is a high school student from Dallas, Texas who helps out other classmates by tutoring them between classes. A tutor is someone who teaches one person or a very small group of students. When Goyal’s high school moved online last spring because of the coronavirus crisis, she decided to also take her teaching online. The 17-year-old junior and three of her fellow students created TutorScope, a service that offers free tutoring services to other children, including younger ones. TutorScope started with a small number of tutors who helped young people in their city. But it has grown into a group of 22 tutors from Texas, Arizona, and Ohio. They have helped more than 300 students, some from as far away as South Korea.
