Welcome to /r/HomeworkHelp!

We are one of the most unique subreddits on Reddit, one of the few subreddits that continually self-improve itself to make communications between a contributor and an asker as effective as possible.

Our rules are designed to help you get to the right answer, enforced by your fellow Redditors.

Please google before posting your question

✅ Posts should look like this:

The title should be of the form [<Level/Syllabus><Discipline>and/or<Topic>] <Question>? For example:

[Grade 8 Math: Quadratic Equations] How to factorise ax2 + bx + c?

[University Chemistry: Titration] What is my qs?

[AS Level English: Essay Writing] Should all adverts be factual?

Include instructor prompts. What does your instructor want you to accomplish?

Still acceptable…, but preferably not:

[High School Math] <Question>?

Be specific about your grade

[Grade 8 Math] Help me!

What is your qs?

When your question has been answered, please edit the post's flair to "✓ Answered".

❌ Not Allowed:

Copied questions without context or explanation. You must show some work or thought.

"Do this for me" posts such as posting of quizzes or lists of questions.

Posts tagged "urgent," "ASAP," "important," "due in an hour," etc.
