Gad's Tutoring Service is headed up by a former Dekalb College teacher. He specializes in undergraduate college math and science tutoring. He also accepts high and middle school students who are struggling with algebra, calculus and other math and science related subjects. Gad's guarantees its work; that is, if students work hard and continue the tutoring sessions through the end of the semester, passing grades are guaranteed. The entrance to Gad's Educational & Tutoring Service is located on East Dougherty Street.
