Mistakes in structure, citations, formatting, spelling, and grammar can cost you points (depending on your instructor’s priorities, of course). So if you want to ace your essay, use this checklist to catch issues before you submit. Don’t worry—we’ve organized it from the introduction to the conclusion, so you can review each section step by step and make sure nothing slips through the cracks.
Introduction
Typically, a strong essay introduction includes a hook, background information, and a thesis statement, though some assignments may require additional context or definitions.
Does It Have a Hook?
Your hook is the opening element—often a sentence or two—that engages readers and encourages them to keep reading. It could be a surprising statistic, a sharp question, a short, relatable moment, or maybe a meaningful quote.
Whatever you choose, make sure it connects directly to your subject and leads naturally into your main idea, rather than feeling random or overused.
Bad hook (Vague, generic, says nothing specific): “Since the beginning of time, people have always communicated.”
Good hook (Specific, important, and leads into a discussion):
“Every day, the average student sends more messages than they write sentences in class, a shift that’s reshaping how we communicate academically.”
Tip: If you replace your topic with another one and the hook still works, it’s too generic. For more tips, check our hook templates.
Is There Background Information?
Background information prepares readers for your thesis. You can place this right after the hook and keep it to one or two concise sentences that go from the general topic to your specific focus.
Steps to write it:
- Ask: What must readers understand before they see my claim?
- Include just the context your reader needs to get your point—skip the long history unless it really matters.
- Move from broad topic → specific issue.
- Keep it to 1–2 focused sentences.
Bad background (Too broad, obvious, unfocused):
“Communication has changed a lot over history. Many inventions helped people communicate. Today, people use phones and computers for many things.”
Good background (Focused, relevant, and leads toward an argument):
“In academic settings, digital communication tools now shape how students research, collaborate, and present ideas. This shift has sparked debate about whether constant connectivity strengthens or weakens critical thinking.”
Do You Have a Strong Thesis Statement?
The main claim of your essay is called the thesis statement. It should be a strong, debatable assertion rather than a single subject or arbitrary fact. You can place it near the end of your introduction.
If you already have a thesis statement and want to strengthen it, consider this:
- Start by turning your topic into a question.
- Answer it with a clear position.
- Include the main reasons and directions your essay will follow.
- Try to avoid vague words like things, many, very, good, or bad—pick more specific words.
Bad thesis (Not impressive, too obvious, not arguable): “Social media affects students.”
Strong thesis (Clear claim + roadmap of supporting points):
“Excessive social media use reduces students’ academic focus by fragmenting attention, encouraging multitasking, and shortening deep reading time.”
Body
The body is where you prove your thesis by presenting evidence, explaining its significance, and showing how it supports your main argument. Of course, it shouldn’t be haphazardly organized—each point should build on the last, creating a clear, logical flow from start to finish. Here is what you need to check:
Does Every Paragraph Have a Topic Sentence?
A topic sentence is a direct and concise explanation of what the paragraph is about. Usually, you can spot it at the start of the paragraph, but it can come slightly later if the paragraph opens with a transition or brief setup. To write one, state your paragraph’s claim directly and make sure it’s specific enough to prove with evidence.
Example paragraph:
Frequent exercise improves focus and memory retention. In fact, researchers found higher test scores and better study habits.
Does It Have a Structure?
Your body shouldn’t feel like a random pile of paragraphs. Most essays follow a recognizable structure that helps readers understand how your ideas connect. Check which of the following patterns your essay uses so your paragraphs feel intentional and logically ordered.
Chronological Structure
A chronological structure presents ideas, as its name implies, in chronological order. It’s very common in history essays, process explanations, narratives, or case studies.
The key with this structure is to show unfolding so readers can follow the sequence without confusion.
Typical outline:
- Event/step 1
- Event/step 2
- Event/step 3
- Result or outcome
Compare-and-Contrast Structure
A compare-and-contrast structure helps readers understand the differences and similarities of two (or more) subjects. But remember, instead of just mentioning pertinent points of comparison, you should explain why they are important. Analytical essays frequently use it to assess theories, texts, or concepts.
Typical outline:
- Introduction of both subjects
- Similarities
- Differences
- Evaluation or conclusion
Alternating
Rather than discussing a single topic at a time, an alternating structure helps you compare topics point by point. This makes it easier for readers to recognize differences right away by keeping comparisons clear and concise.
Typical outline:
- Point 1 → Subject A + Subject B
- Point 2 → Subject A + Subject B
- Point 3 → Subject A + Subject B
- Overall evaluation
Block
In a block structure, you thoroughly cover one topic before going on to the next.
Typical outline:
- Subject A (all key points)
- Subject B (all key points)
- Comparison/analysis of both
Problems-Methods-Solutions (PMS) Structure
As its name implies, this structure starts with identifying the problem, discussing possible methods to solve it, and then presenting the most accurate solution. It’s pretty common in research papers, policy essays, or argumentative writing.
Typical outline:
- Define the problem
- Explain causes or context
- Present methods/approaches
- Offer solutions or recommendations
- Evaluate impact or next steps
Are the Evidences Presented Relevant and Factual?
In argumentative essays, each claim should be supported with factual and relevant data—otherwise it’s just opinion. Ideally, you should use reliable sources such as peer-reviewed journals, academic books, reputable databases, university or government websites, and credible news outlets. Google Scholar can help you find these sources.
What if you got your data from AI? Fact-checking is critical since AI can hallucinate and present inaccurate information.
Tip: If you can’t back up your argument with factual, verifiable data, it shouldn’t be in your essay.
For personal reflection essays, your own experience is enough.
Are Direct Quotes and Paraphrased Quotes Properly Cited?
Ideas, data, or phrasing that aren’t common knowledge should be cited, whether quoted directly or paraphrased.
- Direct quotes need quotation marks and a citation.
- Indirect quotation still requires a citation, but you can skip the quotation marks.
Something to keep in mind, though. Citation rules vary between style guides. So, make sure to confirm with your instructor which one you should use.
APA Style
In the APA (7th edition), in-text citations include the author’s last name and year, and a page number for direct quotes. You must use a parenthetical citation at the end of the sentence, while in a narrative citation, the author’s name is included in the sentence. Here are the full rules on the official APA guide.
Examples of APA in-text citation:
- Parenthetical: (Smith, 2022, p. 45)
- Narrative: Smith (2022) explains that effective study habits improve retention (p. 45).
Chicago Manual of Style (CMOS)
The 18th edition of the Chicago Manual of Style often uses footnotes instead of parenthetical in-text citations. So you place a superscript number after the quoted or paraphrased material, then include the full source in a matching footnote at the bottom of the page. The first note usually contains complete publication details, while later notes may be shortened. Here’s the official guide.
Example of CMOS citation:
- Text: Effective note-taking improves long-term learning.¹
- Footnote: 1. John Smith, Study Skills for Success (New York: Academic Press, 2021), 45.
MLA
In MLA (9th edition), in-text citations include the author’s last name and page number, with no comma between them. Similar to APA, the parenthetical citation is located at the end of the sentence. In contrast, a narrative citation mentions the author in the sentence and only adds the page number in parentheses. Check the official guide here.
Examples of MLA in-text citation:
- Parenthetical: (Smith 45)
- Narrative: Smith argues that consistent revision improves writing quality (45).
Did You Paraphrase Correctly?
The right way to paraphrase shows you understand the source and helps you keep your own voice, but doing it poorly can still count as plagiarism.
Example source text:
Regular reading improves vocabulary growth because exposure to varied language helps learners recognize new words in context.
Incorrect paraphrase:
Regular reading increases vocabulary development since seeing different languages helps students identify new words in context.
Why is this wrong? This version only swaps a few words for synonyms and keeps the same structure and idea order.

Conclusion
Your conclusion is where you restate your main claim (in different words, of course), remind your reader about the key points, and explain why your argument matters.
A strong conclusion includes:
- A reworded thesis.
- A quick recap of the main points.
- Why the argument matters (“so what?”).
- A final closing thought.
