Dear Mr Li,
I would like to express my sincere thanks to you for coaching Ryan during his final year of O Level. If it's not you he would not have picked up his confidence in Physics, Chemistry and A Maths despite attending lessons in tuition centre and previously with other tutors. At the end of Year 3, I can sense he was at the verge of giving up as he admitted that he was pretty lost in these subjects but after attending your lessons, I saw that his confidence slowly returned and he had more understanding of the subjects. I am not expecting him to achieve flying colours but am just glad that he has the confidence to step into the exam hall today. You are his life saviour and both me/Ryan are very glad to have found you. No matter what his results will be, I must thank you for staying with him throughout this critical year and really very grateful for your patience and guidance towards him as you know he is not an easy student.
Mr Li, once again many thanks, I cannot imagine how he would be able to cope 4 subjects (including E Maths) today if without your support!
