My teacher in high school

I'm 25 years old for now and most of period in my life had spent in school. I've been average during my study time but I did well in finish high school. When I was in Grade 10, I couldn't do those courses well and most of them can't pass. My father was so worried but he didn't blame me. Even my school teacher suggested that I should not chose chemistry to learn, which gave me a huge shock. I was disappointed during that time but my English teacher supported me and helped me to get out of this. I approved myself in the final exam in grade 12, which is the most difficult exam in students life. I'm really appreciate my teacher， he is integrity and let me get the hope.
