Assignment 7 Grades Released Sat. Mar 28 by Jerry Assignment 7 grades have been posted to your Gradebook. The CAs reviewed design readmes, validate_heap implementations, and code quality, and you should be able to drill through your Gradebook to read through what they had to say. Should you have any questions about why something was graded the way it was, you should first email your grader, and then email Lisa or me if there's unresolved drama. The median on the assignment was a 106 out of 112, which was a full six points higher than it was last quarter. No doubt many of your benefitted from the extra time, but I'm particularly impressed the scores were as high as they were because everyone was stripped of their ability to hang with other students during in-person office hours.

Lisa and I will be computing final grades tomorrow and Monday, and we'll submit them by Tuesday evening at the very latest.

Be safe and healthy, everyone.

Assignment 7 Deadline: Wednesday, March 25th at 11:59pmWed. Mar 18 by Jerry The university just emailed all instructors with guidelines for final exams, outstanding final projects, and what reasonable deadlines can now be imposed. Assignment 7 is effectively your final project, and Lisa and I have set the assign7 deadline to be this coming Wednesday, March 25th at 11:59pm. We will grade assign7 submissions on Thursday and Friday and return assign grades on Saturday, March 28th.

Lisa and I will hold office hours over the course of the next seven days, and some of our CAs will as well. You can check out the ongoing office hours schedule, which will soon be populated with additional hours beyond those already scheduled.

Assignment 6 Grades Released Wed. Mar 18 by Lisa Assignment 6 grades have been posted to the Gradebook page, along with feedback for the assignments. The median on the assignment was a 79 out of 84. Great job!!!!

Assignment 7 deadline suspended indefinitely, office hoursMon. Mar 16 by Jerry As you may have read in recent hours, the university is mandating that all outstanding deadlines—in our case, the assign7 deadline—be delayed indefinitely until we sense some stability. Frankly, Lisa and I couldn’t agree more. At least for the time being, heap allocators shouldn’t be very high on the must-do-right-now list.

We will be in touch as everything begins to take structure again. You’re more than welcome to work on Assignment 7 if you’d like, of course, but if you have any reason whatsoever to pay attention to more important matters, then you should do so without concern for any deadlines. Restated, CS107 should be the last thing on your mind for the foreseeable future.

Lisa and I will hold some office hours this week, and we’ll try to stick to those we’ve currently scheduled. Given the volatility of the world around us, we may need to reschedule them last minute, but we will try not to. Because there are no looming deadlines now, Lisa and I are no longer requiring our CA's to hold their online office hours. They, like you, probably have more pressing matters at hand.

The university hasn’t mentioned anything about when grades are due, but we will be in touch once we hear more.

Final Exam Week, UpdatedFri. Mar 13 by Lisa Given the urgency of the situation on campus and in Santa Clara County, we have decided on the following updated policy:

The assignment 7 grace period deadline has been pushed back to Friday 3/20, 3:30pm Pacific Time. The on-time 5% bonus deadline of today 11:59pm will not change. Given that many students now have to move out of dorms immediately, and that our assign7 deadline falls on this critical weekend, we have made this decision so that everyone has an opportunity to turn in a heap allocator assignment that they are proud of. Please note the deadline is 3:30pm and not midnight, and this is an absolute hard deadline.

There will be no final exam held on Friday 3/20. We will instead calculate your course grade as follows:

• 17% (original) curved midterm exam
• 15% (original) lab participation
• 35% (original) assignments
• 16% (new) the higher of (95) and (a curved midterm exam)
• 17% (new) weighted average on assign 5 through 7

Updated Assignment 7 deadlinesTues. Mar 10 by Jerry We're living in interesting times :)

Now that the university is strongly urging undergraduates to leave campus, we want to allow everyone to do precisely that if they choose to. Recognizing that traveling, mallocing, and callgrinding at the same time is pretty much impossible, we're extending the on-time-5%-bonus deadline to be Friday at 11:59pm. We also want to be fair to those who've already made sacrifices to meet the original Thursday deadline, so we're going with the following:

• Those who submit by the original deadline of Thursday at 11:59pm will receive an 8% bonus instead of 5%.
  
• Those who submit by the new deadline—Friday at 11:59pm—will still receive the 5% bonus.
  
• Those who submit by the new grace-period deadline of Sunday at 11:59pm can still receive full credit, though there's no bonus.

Final Exam Fri. 03/20 3:30-6:30PM PSTMon. Mar 9 by Jerry The CS107 final exam is on Friday, March 20th from 3:30-6:30PM PST. Please see the final exam webpage for information about the exam, as well as study tips and review materials. The exam will likely rely on a new version of BlueBook for the final exam, and we'll provide a link to the new version as it becomes available. The encrypted file for the exam will be posted in advance of the exam, and you will be notified when it is available. Download the file ahead of time so you are prepared when the exam starts. We will provide a password to unlock the exam five minutes before the published start time, and we'll post that password here and on Piazza.

Course Logistics Update Sun. Mar 8 by Lisa and Jerry (Piazza post announcement) We realize there’s been a lot of recommendations campuswide regarding in-person meetings in light of the novel coronavirus. Here are a few updates about what you can expect in CS107 in the last two weeks of the quarter:

• Helper hours: We will continue holding helper hours as scheduled on the Google Calendar. All CA helper hours will use QueueStatus where you have the option to sign up remotely and talk to course staff over Google Hangouts. Most helper hours will also have physical locations (in Huang or Jerry/Lisa’s office), but course staff who choose to hold remote hours will mark their location as “remote-only” on the calendar event. Edit: As of Monday 3/9, all office hours are remote-only to comply with campuswide guidelines.
• Lecture/lab: We will not hold any lectures or labs during dead week.
• Final exam: The final exam will be administered through BlueBook, scheduled as close to our final exam slot as possible. You do not have to be on campus to take the exam, but you will need a persistent internet connection. More details to be released Monday.
• Final exam review session: We will have a CA-led review session during finals week on Wednesday, March 18th, 12:15-3:15. This session will be recorded. More details to be released Monday.

We appreciate your patience as we figure out how to navigate this situation as a community.

Friday Lecture (March 6th) cancelled Wed. Mar 4 by Lisa In light of the campus advisory against large-scale events, as well as your pressing end-of-quarter deadlines, we've decided to cancel the wrap-up lecture scheduled for this Friday, March 6th. The slide deck is posted here (and on the schedule page) if you're interested in what comes after this course.

Jerry and I will be holding helper hours during the scheduled lecture time (12:30-1:50pm), so swing on by if you have questions about the last assignment. Details about a CA-led final exam review during finals week to follow once we have more info. Thanks! :)
