Homework
Homework will be assigned regularly and due Monday of each week by one minute before
midnight, through Gradescope. Late homework will not be accepted, however, the lowest
homework grade will be dropped when determining the final grade for the class (to be
used for emergency purposes). You can collaborate on solving homework problems,
but, in the end, the problems should be written up in your own words.

For students who take the final exam, your grade will be based on the scores of the
homework, two midterms, and one final exam. It will be calculated from taking the
maximum of the scores defined below:

Score #1 = (10% HW) + (25% Midterm) + (25% Midterm) + (40% Final)
Score #2 = (10% HW) + (25% Best Midterm) + (10% Other Midterm) + (55% Final)
Score #3 = Min of (HW,Best Midterm,Final)

We will curve the final scores for all these students, placing a B-/C+ grade at
approximately the average or median. You cannot pass the class without taking the
final exam.
Exams
• All exams are individually taken, with closed book, closed notes, no calculators or
other electronic devices.
• Roughly half of the exams will be based on material you have encountered before
(such as from homework or lecture). There will be no make-up exams.
• 1st midterm will be on Wednesday, Feb 5.
• Covers up to half of HW #3 (excluding fixed point problem), so up to section 3.3
• Bring pen or pencil and ID
• Extra office hours: Feb 3, Tu 2--2:50pm
• 2nd midterm will be on Wednesday, Feb 26.
• Covers from after 1st midterm to HW #6 (section 6.1)
• Bring pen or pencil and ID
• TA's extra office hours: Feb 25, Tu 4--5pm
• Final exam will be on Monday 3--6pm, March 16.
• Covers everything (up to section 6.4), with emphasis on material after 2nd midterm
• Will not be in-class (per university rules); you will take it remotely
• Exam will be up on our course website at 2:55pm and will be due before 6:15pm on
• Change: open resources (book, notes, online material), calculators and Matlab are
allowed, but you may not collaborate or communicate with anyone other than the
instructor during the exam
• Questions and announcements: by email
• Beforehand:
• Make sure you have a location to take the exam on Monday from 3--6pm
• Have enough blank paper (e.g., blue book), and pen or pencil ready
• Have a way to digitize the finished exam for upload to gradescope
• You may want some sort of clock, perhaps with an alarm set to the exam's
endtime
• Note:
• You will be required to copy down and sign an academic integrity pledge on a
separate sheet of paper
• Start each question on a new page
• A page of formulas will no longer be provided as the exam is now open book
• If you are taking a picture of the finished exam, make sure you have good
lighting, size, resolution, and angle
