Academic Paragraph

In my time as a sophomore i have come across struggles in my academics. My first quarter of 10th grade was when my struggles were most prevalent. The classes I struggled in were SDEV and English. SDEV was a struggle because of the difficult homework assignments, which of most, i did not know how to do and ended in incompletion. English is my other struggle because of my inability to think of ideas for random topics; similar to constant writer's block. Another reason is because of my terrible topic paragraph writing skills. I struggle with the thesis and topic sentences the most in a piece of literature.
