My tutoring experience comes from taking a Secondary 4 (NT) student for English and Science lessons for 6 months. I succeeded in improving his grades from a fail to A (80 marks) for both English and Science. The assignment was ended prematurely due to work commitments where I took on a temporary 6 months full-time job from Nov 2008 to May 2009.
Being extremely dedicated, I will not hesitate to extend tuition sessions free of charge as and when required. I am also flexible with timing and would be happy to accommodate any changes in timing sought by parents.
