The course is carried out through skype or zooms, and the content is to ask or answer questions or find some problems and tell you how to solve them.
I can help you know how to solve problems via a variety of platforms, such as Power Point, videos, online exams and other methods. I could find good problem sheets for you and mark it by myself, analyzing your strengths and weakness and help you improve your mark very quickly.
I have taught some senior students on courses for a year.
