I have helped many Hong Kong students like you prepare for HKDSE and IB SL maths exams. I can answer questions related to your homework, explain key concepts in simple terms, and help you apply the concepts you have learned to solve real-life problems (an important aspect of the IB math curriculum). For IB students who need help with the research paper, including identifying data sources, formulating and testing hypotheses, producing graphs and regression analysis in Excel, and discussing the results, have a chat with me. If you are planning to take SAT/ACT or need advice on applying to universities in the United States, schedule sessions with me. I can help! I have taught economic statistics and econometrics at university and can help you with questions related to your economics and statistics class.
