Dear Mr. President, we are students in Class XXX, Grade XXX in our school, and Mr. X is our head teacher. Under the guidance and drive of ta, the whole class studied hard and made progress in their studies to varying degrees. Since Mr. X became the head teacher, our school has made remarkable progress. Compared with last semester, the average score increased by XXX points, and the comprehensive ranking of classes increased by XX. Some XX students entered the pre-grade 100, and some X students entered the pre-grade 10. These achievements are inseparable from the drive and leadership of Teacher X, and ta's work has won the trust of students. I will be promoted to Grade Y next semester, and I will face the middle school (high school) exam again. New and greater challenges will be the problems we need to face. All our classmates hope to have an excellent class teacher to guide us, and Mr. X is the best candidate in our mind. So we implore the headmaster to let Mr. X continue to guide us and be our class teacher. Under the leadership of ta, we promise to study hard, strive for greater progress, strive for better results in the middle (high) exam, win glory for the school, earn the future for ourselves, live up to the guidance of Teacher X, and live up to the care and support of the principal. Please think about it. Salute to your students: (signature) year month day.
