During my teaching career, I've seen so many students claiming that they "hate" math because it is difficult. This makes me feel sad as math is reduced to boring numbers, formulas, and theories that need to be memorized only for the sake of exams. So to change this, I'll help you understand and appreciate the beauty of math by explaining the logics behind every theory and every technique, by connecting theories to their applications, and by taking baby steps to build a solid foundation. I teach all-level math (A-level, IB), GMAT/GRE math. And lessons can be delivered in either English or Chinese. The length of one lesson is typically 1h. Lessons will be tailored to your needs. Tell me before class what troubles you or how you'd like the lessons to go, and then I'll design the class and materials to clear all your confusion, and help you practice until you have a good grasp of this chapter.
