My difficult OGT

The OGT that I believe I will have the most trouble with would be writing one. I think this because I have trouble explaining my point of view on topics. I also have trouble with explaining the deeper message in smaller messages. I also have problems with my diction and keeping my point throughout essays. I can go to my teacher and ask for extra help before school and after school. My teacher can help me with continuing good diction throughout paragraphs and an essay. I can ask my teacher to give me a topic and write a few paragraphs about that topic and then he can tell me what I have doing wrong. I can also take practice writing OGT online and they can tell me more of what I am doing wrong.
