By the tiswa editorial team, from the official sources listed at the end of this guide. How we write our guides
ChatGPT for computer science students is most useful when you treat it as the patient teaching assistant you never get enough office hours with. It can explain a stack trace, suggest the edge case that breaks your function, or check the complexity you worked out by hand. It hurts you when it writes code you hand in without understanding. This guide is organised around the actual work of a CS degree: programming courses, data structures, algorithms, databases and the graduation project.
The free tools you are entitled to
Your first stop is the GitHub Student Developer Pack. According to the official pack page it includes:
- GitHub Copilot Student for verified students: unlimited code completions, a set allowance of GitHub AI Credits, and limited chat and agent use with the models available through auto model selection.
- Free Pro level access to GitHub Codespaces, a full development environment in the browser that runs from any device.
- Free GitHub Pro while you are a student.
- A free JetBrains student subscription, renewed annually, covering professional IDEs such as IntelliJ IDEA and PyCharm.
- Visual Studio Code coding packs to set up Java, Python or .NET development.
- MongoDB Atlas credits plus MongoDB Compass and MongoDB University.
- Microsoft Azure: free access to 25+ cloud services plus credit, for students aged 18 and over.
Set up Copilot step by step
- Use your university email on GitHub
Create an account with it, or add it to your existing account in settings. It is the fastest route through verification.
- Apply for student benefits
Go to GitHub Education benefits and upload a recent document showing your name, your university and a clear date, such as your class schedule or enrolment letter.
- Wait for approval
Once approved, Copilot Student appears on your account alongside GitHub Pro and Codespaces.
- Install the extension
Add GitHub Copilot to VS Code or your JetBrains IDE and sign in with the same account.
- Tune it for learning
In the first weeks of any course, switch off inline completions while you solve assignments and use chat only for questions. Switch them back on for large projects where they save you boilerplate.
Prompts written for CS work
A good programming prompt gives the full context: language, version, the code, the exact error and what you already tried. Copy these and replace the brackets.
I am a computer science student learning [language]. Here is my code: [code]. Here is the full error: [error]. Do not give me corrected code. Explain what the error means line by line, point to the line most likely causing it, then ask me one question that leads me to the fix myself.
This function solves [problem]: [code]. List edge-case tests with the expected output for each: empty input, a single element, negative values, duplicates, the largest allowed size. Do not change the function. Tell me which case would fail and why.
I analysed this algorithm as [O(n log n)]: [code]. Review my analysis step by step. If it is wrong, point to the loop or recursive call I miscounted, and suggest a data structure that improves it, explaining the memory trade-off.
I have these tables: [tables and columns]. I need [what you want, in plain words]. Write the query, explain each clause, then give me a second query that returns the same result a different way so I can compare them.
Where it helps in each course
| Course | Useful for | Check yourself |
|---|---|---|
| Programming 1 and 2 | Reading errors, concepts like pointers and recursion | You can rewrite the solution from scratch alone |
| Data structures | Walking through tree or heap insertions in text | Trace the steps by hand on a small example |
| Algorithms | Reviewing complexity analysis and correctness proofs | Every proof step is logic, not just wording |
| Databases | Writing queries and normalising tables | Run the query on sample data |
| Software engineering | Unit tests, commit messages, documentation | The tests actually fail when you break the code |
| Graduation project | Repo structure, Codespaces setup, code review | You can defend every line in front of the committee |
Example: fixing a bug without handing over the answer
Your Python function returns the wrong result when the list is empty. Instead of "fix the code", paste the function and the error and ask: "Do not write the fix. Ask me questions that lead me to the bug, and give me one test case that exposes it." You usually find it yourself within two or three questions, and you learn to write tests for edge cases such as an empty list, one element and negative values. Interviewers ask about exactly that skill, and you will not build it if the tool fixes everything for you.
Before internship and job interviews
- Ask for a medium-level algorithms question, solve it on paper before typing, then ask for a review of your time and space complexity.
- Practise explaining one of your projects in two minutes: the problem, the stack, and the hardest decision you made and why.
- Ask the tool to act as the interviewer and ask a follow-up on every answer.
- Prepare your CV with the student CV guide and put your project links near the top.
Academic integrity: the clear line
Many CS departments run code similarity checks, and some courses ban AI tools on individual assignments. Read the course policy before the first submission. The working rule: if you cannot explain a line of your solution to your instructor, it is not your solution. Written exams and lab practicals do not come with Copilot, so leaning on it for homework costs you on test day. For more on detection, see AI detection at university.
A simple weekly routine
- Attempt the assignment yourself first, even if the solution is incomplete.
- Ask the tool only about the parts where you got stuck, and ask for explanations, not code.
- Ask for edge-case tests and run them against your solution.
- Write what you learned in your own words in a README in your GitHub repository. That repository later becomes part of your CV for co-op training.
