I have been tutoring since high school. My students improved their grades significantly, with good feedback on my teaching skill. I have taught IB students math before, and my student had increased her grades from 4 to 6 and another one from 1 to 4. I then continued my tutoring job at university with courses in statistics, qualitative research, business operation, and finance. My student had increased her grades from 7.5 to 8 in statistics, 7 to 8.5 in qualitative research ,5.2 to 8.33 in business operation, and 1.53 to 6 in finance.
