Ice-Breaker! 🧊

  • Turn to people around you! (in around groups of four)
    • Introduce yourselves - share your name, major, pronouns (if comfortable), year, and something interesting about yourself
  • After 5-7 minutes, we'll share this with the whole class!
    • Additional question: What questions do you have on CS @ Cal
  • This is a great opportunity to get to know people in this section!

Logistics 🐈‍⬛

Slides by Antonio Kam (anto@)

Discussions

  • Discussion sections will have more conceptual review
  • We generally won't finish all questions on the worksheet
  • If you have a question at any point in time during the discussion, please ask!
    • Please be respectful of each other
  • Attendance will be done during discussion, and you need to go to 10 out of 12 discussions to get full credit for discussion. (If you want a version of CS 61A without as much guidance, consider a mega section)
    • This means that you don't need to attend every single discussion!
  • Worksheets can be found on cs61a.org.
  • If for some reason you can't make my discussion (due to time conflicts), email another TA, or join the mega section
  • Excused absences: email me!
Slides by Antonio Kam (anto@)

Mega Discussion Sections

  • Can switch to the mega section whenever
    • Just switch on sections tool
    • If you find that this section doesn't work for you, do this
  • Time conflicts - join the mega section, and email your situation to cs61a@, or make a private post on Ed.
  • This section is designed to be larger and have less peer-to-peer interaction
  • Your call on whether you find this section more useful
Slides by Antonio Kam (anto@)

Labs

  • Labs are somewhat similar to discussions, except you code
  • I'll start with a mini-lecture
  • Labs are collaborative!
  • Whenever you have a question, feel free to talk to your peers, or raise your hand up, and I, or one of the lab assistants, will come over
  • Attendance for labs, similarly to discussions, is also required. (You need to go to 10 out of 12 possible labs to get full credit, and also complete the assignments for 1 point each.)
  • To get full credit for labs, you need to attend (1 point), and also submit the lab (1 point)

Office Hours

  • Office Hours
    • My office hours have yet to be determined, but they'll be updated on my website once I know when they'll be.
    • This slide deck will also be updated 👀
  • There are 4 different types of office hours that you can go to in general
    • Advising office hours - not directly related to content
    • In-person office hours - go to a physical room (can work collaboratively!) and join a queue to get help from course staff
    • Online office hours - 20-minute session with course staff for debugging or conceptual questions.
    • Instructor office hours - no questions on assignments, only on concepts
Slides by Antonio Kam (anto@)

Course Assignments

There are 3 different types of assignments:

  • Lab
    • Due date is very close to the day of our synchronous lab.
  • Homework
    • Generally due in on Thursday
  • Projects
    • 4 different projects
    • Generally larger programming projects
    • You can work with someone else on them

Lost on the Moon 🌔 🚀

Slides by Antonio Kam (anto@)

Lost on the Moon

Your spaceship has just crashed on the moon. You were scheduled to rendezvous with a mother ship 200 miles away on the lighted surface of the moon, but the rough landing has ruined your ship and destroyed all the equipment on board except for the 15 items listed below. Your crew’s survival depends on reaching the mother ship, so you must choose the most critical items available for the 200-mile trip. Your task is to rank the 15 items in terms of their importance for survival. Place a number 1 by the most important item, number 2 by the second most important, and so on, through number 15, the least important.

  • Work 5 minutes by yourself
  • Work 10 minutes in groups of 4 (in the group from earlier)

61A General Information

  • This class is not designed for people without prior coding experience
    • Something like AP CS A is enough to get started with 61A
    • If you don't have prior experience, consider taking something like CS 10 or Data 8 instead (CS 10 is recommended)
      • It's still possible to do well in this class without prior experience
      • Prior data has shown that only around 10% of people without prior experience can get a B+ or above
Slides by Antonio Kam (anto@)

61A Resources

  • This class is most definitely difficult, but it also has the most resources out of any CS lower division class here (everything can be found on cs61a.org)
    • Office Hours
    • Tutor Sections
    • Video Walkthroughs/Past Exams
  • Please don't stress 😭

61A Resources

  • I'm also a resource!
    • I took this class in Fall 2021 (very recently!), so I still remember what it was like to struggle through this class, and have seen other people go through those same things.

Please give me feedback on what to improve!

Slides by Antonio Kam (anto@)

- Discussions consist of conceptual reviews (mini-lectures), and more exam-style methodology of solving questions as compared to something like homeworks or labs where you have access to an interpreter - Discussion worksheets are designed to have more questions than we have time for - If you have a question at any point in time during the discussion, *please* ask - if you have a question, it's near certain that somebody else has that same question, so by asking questions, you're going to be helping out everyone in this discussion! - Attendance is done at a random time during discussion - there will be a form that you fill in, and a secret word that you have to input - I will generally know how many people go to discussion, so don't share the code with other people that don't end up going to discussion because I will generally know

- Labs are generally a more hands on version of discussions where you code up the solutions yourselves. - I'll first start off with a mini-lecture covering a bit of the material that you'll need in the lab (will reiterate this during our next lab) - Labs are meant to be collaborative - this is the one coding-based portion of this course where you are allowed to, and in fact encouraged to, communicate to your peers and come up with a solution collaboratively.
