The four rules before you write
- Use their title. "Dear Professor [Last Name]" — not "Dear Sir", not "Hello Dr.", not "Hi [First Name]" unless they have specifically told you to use first names.
- One email, one request. Do not ask three questions in one email. If you need to, number them.
- State your course and student ID in any email where context matters. Professors have hundreds of students.
- Proofread before sending. One grammar error makes you look careless. Two make professors stop reading.
Template 1 — Asking a question about course material
Subject:Question — [Topic], [Course Code]
Dear Professor [Last Name],
I am [Your Name], a student in [Course Name, Section].
I have a question regarding [specific topic from lecture/textbook]. I have reviewed [chapter/slide/resource], but I am still unclear about [specific point].
Would you be available during office hours this week to discuss this, or would you prefer I send my question by email?
Thank you for your time.
Sincerely,
[Your Name]
[Student ID]
Template 2 — Requesting an extension
Subject:Extension request — [Assignment Name], [Course Code]
Dear Professor [Last Name],
I am writing to request a short extension for [assignment name], currently due on [date].
Due to [brief, honest reason — e.g. overlapping deadlines / medical issue], I have not been able to dedicate sufficient time to complete it to the standard I aim for. I have already completed [X portion] and am requesting an extension until [new proposed date].
I understand this is at your discretion and I am grateful for your consideration.
Sincerely,
[Your Name]
[Student ID]
Common mistake
Do not write "I could not do the assignment because I was very busy." Every student is busy. Give a specific, honest reason. If there is no strong reason, ask for the extension anyway — but be brief and respectful, not dramatic.
Template 3 — Asking about research opportunities
Subject:Research opportunity inquiry — [Your Name], [Department]
Dear Professor [Last Name],
My name is [Your Name] and I am a [Year] student in [Department], currently maintaining a GPA of [X.X].
I read your recent work on [specific paper or project — be precise] and found the approach to [specific aspect] particularly compelling. I am interested in contributing to your research group and would welcome the opportunity to discuss any available positions.
I have attached my CV for your reference. Please let me know if a brief meeting would be convenient.
Thank you for your consideration.
Sincerely,
[Your Name]
[Student ID · Department]
The research opportunity email is the one most students write badly. The key difference between a reply and no reply: mentioning a specific paper or project. "I am interested in your research" gets ignored. "I read your 2024 paper on adaptive control for robotic arms and I have been working on a related problem" gets a reply.
