A happy experience you had recently/
An occasion you helped some one with his study or work

Actually, i can remember quite a few occasion when i lent a helping hand for others. The particular event that I would like to talk about was the time when I helped my friends with his study during my college years.

Last year, maybe in May or June, My friend asked me to help him revise advanced mathematics, which is a essential foundation course in college.

Since he dedicated himself to the national robot contest in the past few months, he sacrificed the time that should have been spent on studying other courses.

And considering that the advanced mathematics was quite complicated, he found that the final examination was pretty challenging for him.

Without hesitation, I lent him my lecture notes immediately. Then i summarized several commonly used formulas for him.
I would went to his dormitory to give him some guidance when he encountered some trouble solving the questions.

owing to his hard work and my patient help during that period, he finally pass the exam.
The moment i got his message that he scored 80, I was delight from the bottom of heart.
Additionally, i also had a chance to review the lesson and deepen the understanding of advanced mathematics. As a result, i got a high grade.

This incident proves a old saying：Roses given to others, fragrance left in your hand.
