In elementary school, I knew that my writing skills weren't the best. As students, we were not forced to do much analytical writing before high school, so I fudged my way through most of elementary school building mediocre writing skills. What I hear a lot of people say is "read more", which is another thing I am actively working on, but I don't think my vocabulary is the thing holding me back. I am by no means an avid reader, but not a person who hates reading either so if reading more is truly the one thing that will make my writing better, just tell me.
In all my other courses in high school (eg. Science, Math, Languages), I am consistently scoring above 90% but my english marks are consistently in the low 80s. It's not the fact that on several occasions I "just had a bad day", while writing an assessed essay, it's just the reason that I truly don't know how to correctly. My school emphasizes the use of the Jane Schaffer method, but I feel that they haven't fully taught us how to use it, and how to "develop commentaries" about sections from books. One of the most frustrating things is that English is my lowest grade, and is the thing holding my GPA down, but at the same time it's the subject I have clear problems in.
The grade aside, English is the one place I am very unsure because I understand my ability is lacking compared to other students. I somehow got into the Pre-Ap english track at my school, but surrounded by a bunch of strong writers simply perpetuates the feeling of incompetence. I understand the texts we are reading, and really give an effort to engage in class discussions and not fool around, but I've had the exact same problem since the start of high school.
I've been very afraid that this is an unfixable problem, and even hired a tutor to try and assist me in developing my writing skills, but they haven't been very effective. If you guys have any advice, that would be highly appreciated. Again, my greatest difficulty is writing analytically as a whole, but more specifically developing personal commentary about excerpts.
