Homework & Schedule
Homework Instructions and Policies:
- All homework assignments must be submitted on Gradescope. You may find the link to the Gradescope course page on Blackboard. A video from Gradescope with instructions explaining how to submit your homework can be found here.
- One homework assignment may be submitted up to 48 hours late. This is meant to cover illness, travel, and weeks where you have lots of other work, and you do not need to provide an excuse. Beyond this one, no late homework will be accepted. *Note: to facilitate this, Gradescope will show a deadline and a late deadline for every assignment. It will not prevent you from submitting more than one assignments late, but I’ll only count the first one.
- Leave time to check that your submission is correct. It’s your responsibility to make sure you’ve submitted to the correct assignment, and have uploaded all your work. Plan to submit your work at least 15 minutes before the deadline, and check your submission after uploading it.
- Any calculator, computer program, or online tool (WolframAlpha, chatGPT, etc.) is strictly prohibited.
- Some remarks on writing mathematical proofs can be found here. If you are not familiar with writing mathematical proofs, this should be helpful.
