Who should I contact if I have questions that are not answered below?

Please DO NOT directly email the course instructors using their personal email addresses.

Instead, please e-mail data100.instructors@berkeley.edu and we will get back to you promptly. To ensure more timely responses, this address is monitored by the instructors, head TAs, and multiple lead GSIs.

You should only directly contact the instructors for matters that require strict privacy.

Where is the course website?

Along with our previous offerings, the Fall 2026 website can be found at ds100.org/fa26.

I need an enrollment code/enrollment is too limited/I’m on the waitlist/etc.

The instructors are not able to provide permission codes or any new information about enrollment in Data 100 at this time. Please refer to the Data Science Fall 2026 Courses page and the Data 001 Ed, which includes all information currently available about enrolling in Fall 2026 classes. If you are not able to find an answer to your question there, please email ds-advising@berkeley.edu.

What are the official prerequisites for this course?

The official prerequisites are:

  • Data 8.

  • CS 61A or CS88 or Engineering 7. We strongly recommend either CS 61A or CS 88.

  • Math 54, EECS 16A, Math 56, Math 110, or Stat 89A. This may be satisfied concurrently with Data 100, but we strongly recommend that you finish a linear algebra course before taking Data 100.

As with other enrollment matters, the instructors have no say on this matter, if you have any questions regarding prerequisites, please email ds-advising@berkeley.edu.

Will the official prerequisites be enforced?

The official prerequisites are being strictly enforced by CDSS. Decisions on any requests for exceptions to this policy are being made by the CDSS advisors. To request an exception, see the Data Science Fall 2026 Courses page. Do NOT email instructors about this; we do not make these decisions.

I am a graduate student, but the system won’t let me enroll in Data 100 due to missing prerequisites; what can I do?

Graduate students should use the C200 class code, not C100: C200 has a proper graduate code, so you don’t have undergraduate prerequisite issues. There will be some differences in grading and homework, but the main content is the same.

I am waitlisted. What should I do? What are my chances of getting into this class?

We will update this page if we plan to expand the course. In case we expand the course, it will happen before the first lecture.

I have a Concurrent Enrollment Request that hasn’t been approved yet. What should I do? What are my chances of getting into this class?

By campus policy, we must first process the entire waitlist before we can admit you. We will do all we can to ensure all waitlisted students are promptly admitted so that you can also enroll in the course, though we cannot provide a 100% guarantee that will be the case. But we strongly suggest you start working on the course, following lectures, and turning in assignments from the start. This will prevent you from falling behind and will give you the best chance of success in the class.

Note that once all CE requests are processed (in the first few weeks of classes), we will remove all temporarily added students who do not end up with permanent enrollment in the course.

See above for how to get added to any other required resources.

I am a campus student who wants to audit the course. What can I do?

Most class materials are available online to all campus students, and you can access the lecture videos, slides, etc., without limit. You can also use the generic DataHub to access copies of the assignments, but you need to remove data100. from the beginning of the URL.

Note, however, that the class EdStem, our only other class resource, is reserved for enrolled students and faculty auditors, as homework details and solutions are discussed in that environment. Furthermore, we do not add auditors to bCourses, Gradescope, etc., as our limited instructional resources are reserved for officially enrolled students.

Can the instructors assist me in my enrollment, make an exception for my case, or provide me with an “enrollment code”?

No. There are no exceptions from the instructor’s perspective to the enrollment and time conflict policies stated in this FAQ. If you need assistance with enrollment or think your circumstances warrant exceptional consideration, you must discuss those with an enrollment advisor. They are the only ones authorized to handle such situations and enroll you. See the first question above for more links about enrollment resources.

What is the proctoring/accommodation policy for exams?

Quizterms will be in-person at the Computer-Based Testing Facility on campus and subject to standard their proctoring procedures, with appropriate accommodations for DSP students.

Our Final Exam will be held in-person on campus, and subject to standard their proctoring procedures, with appropriate accommodations for DSP students.

I require specific accommodations. What should I do?

All accommodations in this course are handled uniformly through the DSP Office. If you have a letter of accommodation from the DSP office, we have already received it, and we will honor all accommodations listed in your letter. Please see the syllabus for more details on this topic.

What is the final exam schedule for this class?

The Final Exam is scheduled for Friday, December 18th from 11:30 AM - 2:30 PM PDT.

Data 100 does not allow lecture time conflicts or final exam conflicts.

What is the time conflict policy for the course?

The basic policy is the following:

  • ENROLLMENT TIME CONFLICTS: This class will NOT allow time conflicts.

  • FINAL EXAM CONFLICTS: This class will NOT accommodate final exam conflicts.

There are no exceptions.

What is the Quizterm schedule for this class?

All details are subject to change before the start of the semester. Everything below is tentative.

There are three one-hour Quizterms. We plan to administer them in the computer-based testing facilities on campus.

  • You will have the option to sign up for a one hour slot to take the first quizterm between Monday 9/28 and Thursday 10/1 in the CBTF.

  • You will have the option to sign up for a one hour slot to take the second quizterm between Wednesday 11/4 and Friday 11/6 in the CBTF.

  • You will have the option to sign up for a one hour slot to take the third quizterm between Wednesday 12/2 and Friday 12/4 in the CBTF.

There will also be a mandatory Prerequisite Quiz held at the CBTF between Tuesday, 9/8 and Thursday, 9/10.

We will offer quizterm retakes at the CBTF during RRR Weeek for partial score recovery. The final exam and prerequisite quiz will not have retakes.

Additional information about exams and retakes will be provided once the semester begins, including instructions for students with DSP accommodations.

When will the full schedule of labs and discussions be announced?

Discussion sections will be release prior to the second week of class. You will have the opportunity to indicate your desired sections on the Pre-Semester survey. There will be no lab sessions. See our course policies for more information about labs.

The Fall 2026 website can be found here.

Where is the Class EdStem?

Here!. You will need to be officially enrolled in Data 100/200 to access it.

If your question isn’t answered in this FAQ, please try EdStem next before emailing the instructors.

I can’t find any information on bCourses. Why?

We will only be using bCourses to sync access to Gradescope. As long as you are enrolled in the class right now, you don’t need anything. All class materials are available online through the website; communications happen on EdStem; and computational work is done on the DataHub.

I have added the course later in the semester. Can I catch up? Can I be excused for all the late work?

The answer to the first question is impossible to give in general, as it depends both on how late you add the course and what your own background is. But as a general rule, the course moves quite quickly and covers new ground from the start. We estimate most students will probably struggle to catch up effectively if they join any later than the first few days of the semester unless they have a particularly strong background already in the initial topics (Python and Pandas).

As for the second part of this question (Can I be excused for all late work?), we will not be accommodating extensions beyond our extension policy below (see next question for details).

If you are currently waitlisted/on the fence for adding this course, please see the Enrollment section above.

I didn’t turn in a Lab/HW/etc in time because I had X (illness, etc.). Can I have an extension?

We have a generous slip days policy for assignments. This is meant to allow most students to manage delays that can occur due to illness, accidents, personal problems, etc. You must use your slip days first for any and all circumstances that cause you to be late with an assignment. You should not think of slip days as “free extra days to be late any time.”

Once you’ve exhausted your slip days, we will only provide an extension in case of a major and documented set of exceptional circumstances (death in the family, illness documented with medical paperwork, or similar). In such case, please fill out the Additional Accommodations Form, providing documentation that supports your case. Given the already flexible slip days policy, these exceptions will only be granted sparingly.

I would like to make a class-wide announcement about my project/group/initiative/etc.

We only allow posts made on EdStem, and you must make it yourself. We do not make posts on your behalf. These are our guidelines for EdStem posts from student groups - they must be text-only posts (no videos) where the announcement:

  1. Has to do with teaching or tutoring in a non-commercial setting,
  2. is directly related to the material in the course, or
  3. is seeking to recruit students to help with the public good in a non-financial way (no solicitations for donations!) and in a context explicitly connected to their work in the course.

I would like to apply for a (u)GSI position for this course. What should I do?

All applications for Academic Student Employee positions are managed centrally; you can find all the details here. Please do not email the instructors individually with your resume/etc, as they are not in a position to hire you.

Who do I contact if I have further questions? How do I email the instruction team?

Please e-mail data100.instructors@berkeley.edu and we will get back to you. Note that to ensure more timely responses, this address is monitored by both instructors and the course director. You should only contact the instructors directly for matters that require strict privacy and their direct attention.

We’re excited to have you in the class!

Ramesh (Professor), Jeremy (Professor), Rohan (Course Director), and the Fall 2026 instructional team.
