How to Submit Homework

The homework will be distributed as web pages, linked from the list shown above.

Write your answers in pencil, photograph the pages, and submit them to Gradescope. If you prefer, you can submit answers written in LaTeX, Word, RST, or whatever format you like.

Note: grading is for completeness only, not for correctness. You will receive full credit if I can see that you’ve put in a reasonable effort to find the solution, even if your solution is incorrect.

Solutions will be posted ten days after the submission deadline.

Homework Grading Policy

Written homework is graded based on completion, not correctness.

You are allowed to submit any homework late, with a penalty: your homework grade will be multiplied by \(\max(0.5,1-t/28800)\), where \(t\) is the lateness of your submission, in minutes. For example, if you’re late by one day, you can earn 95% credit; if you’re late by any number of days greater than 10, you can still earn up to 50% credit.

Warning

Warnings about the late penalty

• Gradescope does not show you the late penalty. If you submit late, and want to calculate your grade, you’ll need to calculate the late penalty yourself, based on the ‘lateness’ that is displayed on Gradescope.

• The late penalty is not waived for travel, trauma, interviews, religious holidays, or for any illness or injury that leaves you with the use of your hands.
