Gradescope Submissions, Returns, and Resubmissions

All work for 105L will be submitted on Gradescope. Here are some guidelines, links, and instructions for submission:

  • Once you have completed your work, you need to scan it to a PDF. You should use a document scanner app on your phone. Ideally, you should use the Gradescope Mobile App to submit. You can install that from your phone or tablet’s app store. Instructions for using the app can be found here. You may choose to use a different document scanner app, as as Adobe Scan. However, assignments submitted without a document scanner app are not acceptable. Specifically, you may not simply use your phone’s camera app.

  • When logging into Gradescope, be sure to use the ‘School Credentials’ button:

    login screen with school button highlighted

    (You can instead log into Gradescope via Canvas if you wish! That will log you in automatically.)

  • After you’ve logged in, find the correct assignment in the Assignments area, and follow the instructions here. Most of the assignments in 105L will require you to assign questions to pages. If you do not do this, your work will not be graded until you fix it.

  • Each question will be scored 1 (perfect), 0.9 (minor error), 0.5 (partly correct), or 0. Each question will get commented upon. You will then use comments to correct your work and resubmit.

  • Each assignment will have a separate resubmit Gradescope assignment:

  • After you resubmit, graders will regrade each question you ask them to regrade by using the ‘Regrade’ checkbox below each question number. Once resubmissions are returned, you will get a ‘pass’ or ’no-pass’ on each assignment. You will get an email from me if you did not pass an assignment. Pass/no-passes will also be recorded in the Gradebook on Canvas.

Getting Help

You will need help with this class! Everyone will. Math at Duke is challenging, and this class will ask a lot of you, regardless of your math background. There are many resources available for help. Here’s an outline with links:

  • Help Room: Located in the Classroom building (Room 137), the help room is open around 25 hours a week from 5-10pm Su-Th. It is staffed by TAs, graders, and others. You can go at any time to get help with your work. You can go do homework there and get help when you need it. It’s a great space to have quiet work time, but have help readily available.
  • Office Hours: I will have two hours of in person office hours, and one hour of virtual office hours per week (see hours above). Here’s a Zoom link for the virtual office hours.
  • Individual meetings: I’m available to meet one on one in person or by Zoom as needed. Drop me an email! I’m also available for quicker questions before/after class.
  • The Academic Resource Center: Duke’s ARC provides multiple layers of support for classes. From peer tutoring to study groups, this is one of the most useful resources Duke provides. Make an appointment with an advisor there, or sign up for a study group!

Syllabus

The table below lists all topics, assignments, and extra resources for 105L this semester.

The Assignment column links to the PDF of the day’s worksheet or lab, or to an online assignment. Resources, such as lab spreadsheets, needed external websites, or extra videos are linked in the Extra Resources column. Lab PDFs are linked in the relevant lab’s entry in the Topic column.

Worksheets are to be handed in on Gradescope the Monday of the week after they are assigned in class, by 8am. Worksheet regrades are due the Tuesday after worksheet assignments are returned, also by 8am.

Textbook sections containing material relevant to a given day’s class or lab are listed in the table below. It is recommended that students read the relevant textbook sections. Questions at the end of textbook sections may be done as background and supplementary material. Solutions to all textbook questions can be found on Canvas in the File area. No questions from the textbook will be collected or graded.

All assignments have due dates listed in the table below. Note that all assignments are due by 8am on the day listed.

Following each class day, the numbers in the ‘Day’ column below will become video links to a recording of the lecture within 24 hours.
