Please help me amend this. Thank you.
When I was 17 years old, I decided to learn English by putting in more effort, because my English is very poor and I have a low score in English. It was a challenge because my foundation of English is weak and I know little about English grammar and English pronunciation. But I didn't give up. I know it is a challenge I have to face. So I got up early to read English texts and recite words every day at that time. I also wrote English papers every day. Through my hard work, my English has improved at last. This is my challenge story.
