Sergey Bizikin successfully completed Calculus One, a one semester introduction to differential and integral calculus covering limits, derivatives, and integrals, through Coursera with distinction. The course was offered online by The Ohio State University's Department of Mathematics and lectured by Bart Snapp, PhD, Bareis Lecturer, and Jim Fowler, PhD, Lecturer. However, this online course does not reflect the entire curriculum or confer credit, grades, or a degree from The Ohio State University.
