Got an unexpected tutor challange!

From the first day of second term, the mock exams have started for year 13 and 11. I still remember about my mock exams, I re-learned all the topics some points that I did not understand. My friend is also at the same position now. She is in year11, suffering with mocks, she asked something about maths. We both from Japan, so we can communicate in Japanese which makes the explanation and understanding a bit clearer. So we did some exercises related to vector which was one of my dislike topic last year. There are some confuse about this topic such as where to start from. We made it clear and she said she can solve the question about the vector now! We also studied about interest questions. There are two types of interest on the exam in IGCSE which are compound and simple. She did not really studied about it since she came to the school not from the beginning of the two year course. So I told her the equation and how to remember it. She looks feeling great to become able to do these questions. It was only about 30minutes when we were waiting for our parents playing hockey after we've done with our practice though, I believe that we made a quite good effort for maths exam. I also hope that it helped her preparation and helped my explanation skills as well.
