    • The tutors are here to help you with concepts, to go through examples with you, and to help you learn how to solve problems that you get stuck on. That means you should NOT ask them for homework or project help. Please go to office hours for that.
    • Please take note of a few things, if you choose to sign up for tutoring:
      • Try to list as many times you're available as possible! This will help in receiving a tutoring appointment.
      • Similarly, filling out the feedback form within 48 hours is required for you to receive future appointments.  Please be constructive!
      • Check your email in a timely manner this coming weekend. If a tutor contacts you, please reply within 24 hours to their offer, otherwise your appointment may be cancelled at the tutor’s discretion.

    Week 5 Survey

    CSM Sign Ups

    There are a lot of available sections on Friday: http://scheduler.csmentors.org/. Computer Science Mentors (CSM) will be running small group discussion sections for CS 61B this semester!

    The CSM adjunct section is an additional discussion section with smaller groups that offers more individual attention than is available in large classes. The discussion sections will feature worksheets which cover selected topics from CS 61B. The worksheet will typically follow material presented in lecture a week before the section. The purpose of these sections is to create a stronger feeling of community in classes and reinforce conceptual understanding of course material. Please refrain from asking questions pertinent to homework, projects, and exams during sections. More info: @1064

    Mentors are not necessarily official course staff but are fellow undergraduates who have taken CS 61B and are volunteering their time and energy to create a better community for students. Mentor bios are available here to help you choose a mentor.


    CSM will be reserving some CS 61B sections for students in EOP, a program on campus that supports students who have low incomes, are first-generation college students, and/or who are historically underrepresented. If you are a student in EOP and are interested in enrolling in one of these sections, please use this form to indicate your interest.

Example: if you queue up at 10:55 a.m., but OH start at 11:00 a.m., then you will be removed. You must add a good, specific description to your OH ticket (including your question, any errors, and what you have tried already) or else you will be skipped. Begin your description with an appropriate tag from the following: [Logistics], [Git/Setup], [Conceptual], or [Debugging]. We reserve the right to not help you debug until you have shown effort to debug by yourself. This includes writing your own tests and using the IntelliJ debugger.

  • Discussion and Lab Changes

    Discussion and Lab Permenant Changes

    Discussion 150 (Tuesday 5pm, 9 Evans) will now be taught by Carlo and will be converted from an exam prep section into a regular discussion section. Sam will be teaching exam prep at the same time in B1 Hearst Field Annex.

    Lab 129 (Tuesday 5pm, 277 Soda) will now be taught by Danny and will be converted from a regular lab into a challenge lab.

    Lab 133 (Thursday 5pm, 275 Soda) will now be taught by Eli and will remain a regular lab.

    Lab 145 (Friday 1pm, 271 Soda) will now be taught by Itai and will remain a challenge lab

  • Project 1A walkthrough

    The project 1A spec now contains a video walkthrough for the trickier constructor for LinkedListDeque and ArrayDeque. See https://piazza.com/class/jqr7hfmf4v74e?cid=1010 for more details.

  • Mentor GSIs, extensions, week 2 survey
    1. The mentor GSI selection system is now live. You can request your mentor GSI by going to https://beacon.datastructur.es and using the drop down menu at the top of the page. Your mentor GSI will keep an eye on your progress, approve extension requests, and direct you to resources if it seems like you might be struggling. The system is first-come, first-served. Once a GSI has 35 mentees, the system will no longer let you add that person as a mentor GSI. You’ll be free to switch whenever you want during week 3, but we’ll require manual approval for switching starting week 4. If the person you want is already taken, pick someone else for now, and if you really want a particular person, we can manually add them as your mentor GSI during week 4.

    2. The week 2 survey is posted to the site. Reminder that it will close at 11:59 on February 3rd.

    3. If you need an extension request for project 0 or lab 2, please use the extension request system at https://beacon.datastructur.es. Since the deadlines have already passed, your extension will have to be approved manually, but we’ll be pretty friendly. We’re requiring manual approval because we want to keep track of folks who look like they’re running behind for whatever reason, even if it’s just that you forgot to submit before the deadline. It’s easy to get lost at Berkeley, especially in a class of 1700 people.

  • Pre-semester Advising Sessions

    We are opening up early semester advising to give students a chance to talk to TA’s one-on-one about concerns about the course, declaring majors, and more. We have a wide range of experiences and backgrounds represented by the CS61B staff, so if you want to talk about life beyond CS61B (i.e. internship recruiting, research, co-curricular clubs/activities, etc.), you’re welcome to sign-up for a one-on-one as well. This will also be a great chance to get to know the course staff before indicating your preferences for your Mentor GSI! You can see information about each staff member here.

    You can claim an appointment slot through here. Please be courteous of your classmates and only sign up for one appointment slot. Also, if you need to cancel, please delete the event off of your own Google Calendar so that another student may claim that slot. You may sign up for a slot with any TA you desire. The location will be listed on the particular slot, or the TA will reach out to you once they have found a place. If you want to meet with a TA who doesn’t have any slots available, you can try sending them an email! Please do not use one-on-ones for the purpose of homework/project/lab help, debugging, specific conceptual questions, etc.

  • Pre Semester Survey

    The pre-semester survey is now available, sorry it’s a day late. Fill it out at https://goo.gl/forms/v2aZJLLZwA52lcQJ2. This will add 8 extra credit points to your total score (see about page on the website for more about points in the course).

    We’ll accept responses until roughly the first midterm, but an earlier response is welcome so we can reach those of you have specific requests or needs.

  • Soft Launch

    The main part of the website is now posted. Calendar subject to change after week 4, though the midterm dates and times are set. If you want to try to get started on assignments, you can try to use the sp18 versions, but official support won’t be provided. Hoping to post the first few assignments by 1/14 for people who want to get started early.

    Course policies and other administrative stuff coming later.

RRR Week (May 6-10)
Finals Week (May 13-17), Final exam: TBD
Lab/Discussion Schedule

Each discussion section is now a regular, an exam-prep, or a LOST discussion section.

  1. Regular discussions will focus on reviewing the material and doing foundational questions.
  2. Exam-prep discussions will have less review of concepts and focus on working through exam-level problems.
  3. LOST sections will be special drop-in sections that assume no prior knowledge and will be a safe space for students who are feeling behind.

Each lab section is now either a regular or a challenge lab section.

  1. Regular lab sections will follow closely with course material and applying what you learn in lecture.
  2. Challenge lab sections will focus on interesting collaborative puzzle solving programming challenges that are meant to prepare students for trickier exam problems.

 
Office Hour Schedule
Note: Office hours before lecture on Monday, Wednesday and Friday are in 109 Morgan. Office hours before 2 P.M. on Tuesday are in 310 Jacobs. Office hours after 5 P.M. on Tuesday and Wednesday are in 400 Cory. On Wednesday, Thursday, and Friday, feel free to come to lab with your questions.
