Midterm Quiz: Monday-Tuesday July 20-21, 5PM-5PM PDT
Final Quiz: Friday-Sunday Aug 14-16, 5PM-5PM PDT
Each quiz will be a 24-48 hour open book, open note exam. Quiz material will approximate about 2-4 hours of active work (depending on your preparation and process), and we give you 24-48 hours to work on each quiz to reduce time pressure and accommodate any difficulties accessing resources during your quiz time.
Unlike the problem sets, the take-home quizzes are strictly individual work. Even course staff assistance will be limited to clarifying questions of the kind that might be allowed on a traditional, in-person exam.
If you have questions during the exam, please ask them via our discussion forum. All office hours are cancelled/moved quiz days.
These quizzes are intended as checkpoints for yourself for how well you understand the concepts in this class. By giving you ample time to access course resources, we hope this experience will help you structure your learning for the rest of the quarter.
The take-home exams are open-book (open lecture notes, handouts, textbooks, course lecture videos, and internet searches for conceptual information, e.g., Wikipedia). Consultation of other humans in any form or medium (e.g., communicating with classmates, asking questions on forum websites such as StackOverflow) is prohibited. All work done with the assistance of any external material in any way (other than provided CS109 course materials) must include citation (e.g., "Referred to Wikipedia page on DeMorgan's Law for Question 2."). Copying solutions is unacceptable, even with citation. If by chance you encounter solutions to the problem, navigate away from that page before you feel tempted to copy. If you become aware of any honor code violations by any student in the class, your commitments under the Stanford Honor Code obligate you to inform course staff. Please remember that there is no reason to violate your conscience to complete a take-home exam.
The exam will be posted on this webpage at 5PM (Pacific time) the day the exam begins. You will upload and submit your submission as a PDF to Gradescope. Just like we do for homework, we will provide a LaTeX template if you find it useful, but we will accept any legible submission.
The Midterm Quiz Gradescope assignment portal will also be published at 5PM (Pacific time) the day the exam begins. You can submit multiple times, but we will only grade the last submission submitted by 5PM (Pacific time) the final (second) day of the exam.
No exam submissions will be accepted late. Please double-check that you submit the right file. Please tag your questions.
Material covered: The Midterm Quiz will cover all material through (and including) Lecture 11 (independent random variables).
Review session: Tim, one of our wonderful TAs for CS109 this quarter, held a review session last quarter. Zoom link below.
Practice material: Previous iterations of this course have had a midterm that may have covered slightly different material than you are responsible for. To help you practice the concepts for our Summer 2020 midterm, we have provided these previous midterms in whole. Feel free to post on Ed to clarify whether a certain question from a practice midterm covers material that will be on our Summer 2020 midterm.
These review materials were put together by Alex Tsun, a CS109 TA. These materials may cover slightly different material than you are responsible for. You only need to learn what is in the lecture notes/slides through independent random variables. Be careful not to mix up discrete uniform and continuous uniform RVs!
Material covered: The Final Quiz will cover all CS109 material, but is focused on the material after Lecture 11.
Review session: Tim, one of our wonderful TAs for CS109 this quarter, held a review session last quarter for a similar (but not exhaustive) quiz. Zoom link below.
Practice material: Previous iterations of this course have had a cumulative final. To help you practice the concepts in Summer 2020, we provide several of these below.
