Methods Strongly Etched In My Mind! 老师，谢谢您！

The methods that Mr Zach teaches for Mathematics are really helpful, and some of them are strongly etched in my mind, and they do help me in my exams and tests. He also taught me highly effective strategies which I am grateful for, because it saves my ink and lead, and eraser dust. And its good that he understands children well, and us adolescents (aged 10-12), if not, I think he'll lose his temper on every session he tutors me. Thank you very much for tutoring me! I won't forget your teachings, even in a sesquicentennial (150 years. Cool, huh?).

P.S. The jokes are ingenious as well. It is good for the left brain who wants attention after keeping quiet for the right brain. 谢谢您！
P.S. Thank you for being very patient.
He should really quit frowning. It's very scary. Otherwise, there's nothing I'd like to 'complain' about.
