I tutor several math courses which include algebra, statistics, probability and calculus, and I ensure that the students perform excellently in their exams. I like to encourage students to ask questions and really understand subjects. I usually give out test samples that are easy for them so that they do well. When they see their score, they start to believe they can do it. This is a huge confidence booster. I'll continue to add just one or two challenging questions but continue to make it doable for their level. I evaluate students' performance, behavior, social development and physical health. I enhance student learning by optimizing wide range of instructional approaches and innovative activities. I evaluate and revise course content to facilitate and moderate discussions and student centered learning.
