How to Write a Literature Review for Your Final Year Project
Your supervisor says, “Send me the literature review by next Friday.” You nod like you know exactly what that means. Then you go home and google “what is a literature review”.
No judgement. Almost nobody is taught this properly before their final year project (FYP), yet it’s one of the chapters supervisors care about most.
What a literature review actually is
It’s not a list of summaries. That’s the biggest mistake.
A literature review shows what’s already known about your topic, where researchers agree or disagree, and what’s still missing. That missing piece, the research gap, is what your project fills.
Think of it as telling a story: “Here’s what people have tried. Here’s what worked and what didn’t. Here’s the question nobody has answered yet, and that’s what my project does.”
Step 1: Find 15 to 25 relevant papers
For most undergraduate FYPs, this is enough. Good places to look:
- Google Scholar, sorted by recent years.
- Your university’s HEC Digital Library access (if you’re in Pakistan) or your library’s database login.
- The reference lists of good papers. One strong recent paper can point you to ten more.
Prefer papers from the last five to seven years, plus a few classic older ones everyone cites.
Step 2: Read smart, not everything
You don’t need to read every paper cover to cover. For each one, read the abstract, introduction, conclusion, and skim the results. Then note:
- What problem it tackled
- The method used
- The main finding
- Its limitation (often in the last section)
A simple spreadsheet with those four columns will save you days. If a paper is heavy going, run a section through the AI Text Summarizer to get the gist, then go back and read the parts that matter.
Step 3: Group papers into themes
This is where it becomes a review rather than a list. Look at your spreadsheet and group papers that tackle similar ideas.
For example, an FYP on crop disease detection using mobile apps might have themes like:
- Traditional image processing methods
- Deep learning models (CNNs)
- Mobile and offline deployment
- Datasets and their limits
Each theme becomes a section.
Step 4: Write each section around comparison
Weak: “Ahmed (2021) used a CNN. Khan (2022) used a CNN. Lee (2023) used a CNN.”
Strong: “Several studies used CNNs for leaf disease detection (Ahmed, 2021; Khan, 2022), reporting high accuracy on lab images. However, Lee (2023) found accuracy dropped sharply on photos taken in real fields, suggesting these models don’t generalise well.”
Notice how the strong version connects papers and points to a problem.
Step 5: End with the gap
Finish the chapter with a short paragraph that says what’s missing and how your project addresses it. For the example above: “Few studies test lightweight models on field images from South Asian farms. This project fills that gap by…”
This paragraph is what makes your supervisor nod.
How long should it be?
It depends on your department, but for undergraduate FYPs it’s usually 2,000 to 4,000 words. Ask your supervisor. Seriously, just ask.
Tools that help
The Literature Review Writer can draft a structure around your themes, which is handy when you’re staring at 20 papers and no plan. Use it as a skeleton, then fill it with the papers you’ve actually read and your own comparisons. Keep every reference tidy with the Citation Generator as you go, not at 2 a.m. the night before submission.
FAQ
Can I cite websites? Sparingly. Supervisors prefer journal articles and conference papers.
What’s the difference between a literature review and background? Background explains the topic. The literature review evaluates existing research on it.
