ACT score of 3 - what you're doing now:
The essay shows some understanding of the task. The essay takes a position on the issue but does not offer a context for discussion. The essay may acknowledge a counterargument to the writer's position, but its development is brief or unclear. Development of ideas is limited and may be repetitious, with little, if any, movement between general statements and specific reasons, examples, and details. Focus on the general topic is maintained, but focus on the specific issue in the prompt may not be maintained. The organization of the essay is simple. Ideas are logically grouped within parts of the essay, but there is little or no evidence of logical sequencing of ideas. Transitions, if used, are simple and obvious. An introduction and conclusion are clearly discernible but underdeveloped. Language shows a basic control. Sentences show a little variety and word choice is appropriate. Errors may be distracting and may occasionally impede understanding.
ACT score of 4 - the minimum you need to aim for:
The essay shows an understanding of the task. The essay takes a position on the issue and may offer some context for discussion. The essay may show some recognition of complexity by providing some response to counterarguments to the writer's position. Development of ideas is adequate, with some movement between general statements and specific reasons, examples, and details. Focus on the specific issue in the prompt is maintained throughout most of the essay. The organization of the essay is apparent but predictable. Some evidence of logical sequencing of ideas is apparent, although most transitions are simple and obvious. The introduction and conclusion are clear and somewhat developed. Language is adequate, with some sentence variety and appropriate word choice. There may be some distracting errors, but they do not impede understanding.
In the description of level 3, I've put in bold the areas you need to work on ... to correct.
I've already told you about your need to use transitions, but I saw no changes in your last two practice essays.
I've told you about your need to have SPECIFIC examples, not just general statements. Here, too, I saw no changes.
Here's what I mean about including specific examples:
Plagiarism is a form of cheating because the student uses other people's ideas without giving proper credit. For example, a student may find a very well written paragraph defining colonialism for a history paper, so he copies the entire paragraph, but fails to say who originally wrote it and the exact source (in a book or online, perhaps).
Taking someone else's idea is a crime. Many songwriters have sued bands and singers, such as Lady Gaga and for stealing the lyrics and/or music of the original song, and many have won their lawsuits.
