I have two years of experience in teaching both Primary and Secondary School students.
After giving tuition to a Primary 2 student, his grades improved drastically. From failing badly in the English listening comprehension and reading comprehension components, he not only passed with flying colours for his final year examinations but obtained full marks for the listening comprehension component.
After giving tuition to a Secondary 5 student, her English grades improved drastically from D7 to B3 in the 'O' level exams.
