I've had 3 years experience in tutoring but stopped for 4 months because of National Service.
I am know holding a stable post in the SAF and can afford time for tuition in the evenings and on weekends.
I tutored 2 students who were PRC (People's Republic of China) nationals and improved their English Language grades tremendously. One improved from Band 4 to Band 2. The other improved from Band 3 to Band 2.
