Supplemental Instruction (SI) and Supplemental Tutors (ST) target traditionally difficult classes and provide regularly scheduled, out-of-class, group study sessions led by fellow UNT students. Students help each other pass "killer courses", such as algebra, political science, music theory, economics, accounting, history, Spanish and world literature. Students who recently did well in a course are hired to sit through that particular course again and lead formal study sessions for others in the class. These non-remedial, peer-assisted programs are very successful. Students who attend the sessions make between a half to a whole letter grade better than those who do not attend. ST focuses on Math 1010, covering every section, while SI covers courses in different disciplines. Please check the Learning Center's website, http://www.unt.edu/lc, to find out which sections will be covered, or contact the Learning Center staff at (940) 369-7006.
