Within the last four years, I have conducted six different tutors on diverse areas of study. Using my prior experience and knowledge on school work and standardized tests, I was able to assist students from different background with the most efficient approach.

  • Introductory English Language - Student Lee Student Lee is a nail-art specialist living in Korea. She was new to English, so I carefully planned and executed an introductory course on English Language, focusing specifically on reading comprehension and communication skills. This course was conducted face-to-face for three consecutive hours each week, and sources used during the lecture include the Magic Tree House series and the Percy Jackson series.
  • Scholastic Aptitude Test (SAT) - Student Han Student Han is currently a senior in High School. The sudden decision by his parents to move abroad left this student lost, unable to figure out how to ace the SAT without prior knowledge. I have conducted a well-organized online tutor session with all my effort, ultimately enabling the student to achieve one's dream score within few months.
  • TOEFL iBT- Student Peter, Yuna, Jiwoo, Taelin, Seoyoung, Jihoo, Seehyun As a student who received a superscore of 118 in the TOEFL exam during High School years, I was able to design the most efficient yet effective form of education despite the limitations of online lectures. Lucrative guidance allowed for students from different knowledge level to familiarize themselves to the examination, thereby enabling each student to be prepared for the actual exam.
  • Algebra and Geometry Course - Student Jack Using my knowledge in Calculus and Statistics, I was able to assist Jack in his freshmen mathematics course. Dealing with concepts ranging from linear algebra, shapes, and statistics, student Jack displayed a rapid incline in his mathematics grades and was fully satisfied with the tutor session.
