Give me an answer why I failed more than 3 grammatical errors

It seems that there may have been some confusion or misunderstanding in the task you were attempting. A potential answer for why you failed to avoid more than three grammatical errors could be: "I struggled with my writing due to a lack of focus and attention to detail. I may have rushed through my work without properly proofreading, leading to multiple grammatical errors. Additionally, I might not have fully understood some of the grammar rules, which contributed to my mistakes. I plan to improve my writing by reviewing the rules more thoroughly and practicing regularly to enhance my skills." If you need specific feedback on your writing or assistance with grammar, feel free to share an example, and I'll be glad to help!
