how to email
a professor

this is worth getting right because it is the cheapest help available to you and most students never use it. it is also a transferable skill — the same email works on a manager in five years.

put the course in
the subject line

"CHEM 201 — question about problem set 4" beats "question" or, worse, "hi". they teach several courses and your name means nothing out of context. the subject line is how your email gets sorted into the right mental pile instead of the bottom of one.

say who you are
in one line

course, section, and your name. not a paragraph of apology. "i am in your tuesday 10am section" is enough and it costs you nothing.

ask one specific thing

"can we meet" puts all the work on them: they have to guess what you need and how long it takes. "i am stuck on the second step of q4 — i think i am misreading what the constant represents" can often be answered in two lines, sometimes without a meeting at all.

show what you tried

it proves the question is genuine and it shows where your reasoning went. it also, honestly, changes how the reply is written — an email that demonstrates effort gets a more generous answer than one that does not.

email before the
deadline, not after

instructors have discretion and nearly all of it is exercised in advance. a short, honest message two days early lands very differently from an explanation the morning after. this is the highest-value paragraph on this page.

subject: CHEM 201 — q4 on problem set 4

hi professor ___, i am in your tuesday 10am section. i am stuck on q4. i set it up using the ideal gas law and got 2.1 atm, but the units do not work out and i think i am misreading what n refers to here. is there something i am missing about the setup? photo of my working attached. thanks — [name]

short, specific, shows the attempt, asks one thing. the same shape works for a tutor — see asking a question that gets an answer.
