## Lecture 42: The End
- [Lab 11](../labs/lab11/index.html), on Graphs, is *mostly* done
- The pre-lab is open until 8 am tomorrow -- see the Piazza post for details
- Lab 12 status:
- No pre-lab!
- The in-lab will be a survey; if you fill it out (regardless of what your answers are) you will get 10/10
- It will be available late tonight or early tomorrow, and is due by the end of the day on Tuesday
- You can use the lab time on Tuesday to also study for the final
- Office hours are back in full swing
- TA office hours are 5pm - 11pm on Sunday, Monday, Wednesday, and Thursday
- Faculty office hours are M/F 9:30-11 (Bloomfield @ Rice 402) and W 12-1:30 (Floryan @ Rice 203)
- Office hours will end next Tuesday; there will be some type of office hours during the start of finals week -- more info on that later
- Course links are on the Collab landing page
- [Anonymous feedback](https://collab.its.virginia.edu/x/JunIx3)! It's through Collab
- [Readings](../docs/readings.html) are optional, and are posted in the git repo
- The [lectures page](lectures/index.html) has pictures of the chalk board from lectures
- This link can be found on the [UVA page in the repo](index.html)
- Today we start (and finish) [esoteric programming languages](../slides/13-esoteric-pls.html#/) and then the [course conclusion](course-conclusion.html#/)

## Final exam information
- It is 7pm to 10pm on Tuesday, December 14th
- You cannot take it early
- Only those who have let us know they have conflicts can take it at an alternate time
- We'll get back to you in a day or two about the alternate time
- You must bring your UVA ID to the exam!
- Location:
- Floryan's section (11am) will be in the lecture classroom (Ridley G008)
- Both of Bloomfield's sections (1pm and 2pm) will be in Physics 203 & 204
- We expect there to be TA office and professor hours later this week, and we will post about those once we know the details
- There will be a (Zoom) review session -- likely Sunday evening starting at 8pm, but specifics to follow
- We *hope* to have it graded by Wednesday evening, but no promises
- Previous exams are in the repo on the [exams page](../exams/index.html)
- We still don't have solution keys
- Regrades will be more constrained, as it's the end of the semester
- We are going to have a much shorter regrade window (like 24 hours); we'll email the class when that's started
- We will have much less patience for frivolous regrades

## Regrades
- You can submit a regrade request if we mis-graded your exam
- Submission is through Gradescope
- You need to expalin clearly (and BRIEFLY) why your answer should get more credit
- Did you lose points because your exam was hard to read?
- The scanner had some issues with exam writing that wasn't dark enough
- Please type up what you wrote in the exam regrade, and we'll regrade it without penalty
- If you can't read it either, we'll look up the paper exam
- If you submit regrades that do not get points back, we reserve the right to LOWER your overall exam grade
- We are trying to prevent frivolous regrades, and to prevent everybody from having us regrade their entire exam when it was graded properly the first time
- Regrades open today (Frdiay, 10/1) at 3pm, and close about 10 days later (Monday, 10/11) at the end of the day
- Regrades will not be accepted outside that time window
