Frequently Asked Questions

TODO: refine questions to match the Data 100 FAQ.

Below are quick answers to common questions. For full details, see the Syllabus.

  • What are the prerequisites? Multivariable Calculus (MATH 53), Linear Algebra (MATH 54 or equivalent), and Probability/Discrete Math (COMPSCI 70 or equivalent). You should be comfortable with vector calculus, matrix operations, probability, and Python programming.

  • When and how are lectures and discussions run? Lectures are Tuesdays and Thursdays, 2:00–3:30 PM. Participation is via in-lecture polls (synchronous) or an asynchronous link after lecture; graded on completion. Discussions are 1 hour on Wed/Thu; ungraded but highly recommended.

  • How are homeworks structured and when are they due? There are 5 homeworks. Each has two parts: Part 1 (Warmup) and Part 2 (Main). Both parts are released together. Deadlines are 11:59 PM Pacific on posted dates. Submit on Gradescope (written and/or coding portals as applicable).

  • How do slip days work? You have 10 total slip days across all homeworks, with a maximum of 4 per homework. Slip days apply automatically by submission timestamp; any amount late up to 24 hours counts as 1 slip day. After 4 days late, submissions aren’t accepted without approved accommodations.

  • Are there alternate exams? No. There are two in-person exams (Midterm and Final). See the Syllabus → Exams for dates and policies.

  • What is the graduate final project (CS 289)? A team-based project in the second half of the semester; details announced mid-semester.

  • How is the course graded? CS 189: Homework (35%), Midterm (25%), Final (30%), Lecture Attendance/Participation (10%). CS 289: Homework (30%), Midterm (25%), Final (25%), Lecture Attendance/Participation (10%), Grad Project (10%). You must earn at least a 50% weighted average across the midterm and final to pass.

  • How do regrade requests work? Allowed for written and autograded components where the rubric/application is incorrect. Submit within one week of grade release (Gradescope for written; a form for autograder issues).

  • What is the collaboration and academic honesty policy? You may discuss ideas/approaches with peers, but all solutions and code must be your own. Do not share solutions or use unauthorized resources. See Syllabus → Collaboration Policy.

  • How do I get help or contact staff? Office hours are on the Calendar. Use Ed for course Q&A and announcements. For sensitive matters, email the staff at cs189-instructors@berkeley.edu.

  • How do additional accommodations and DSP work? Use the Additional Accommodations Form for situations not covered by slip days. DSP students receive approved extensions (2-day automatic extension on homeworks). Extension + slip days must be ≤ 7 days without a required meeting. See Syllabus → DSP Accommodations.
