## Lecture 42: The End
- Office hours are listed on the [Google calendar](https://t.co/9kRXZnqkxZ)
- TA office hours: 6-10 on Sun / Mon / Wed / Thu in the Thornton stacks
- Bloomfield's: M/W 1-2:30 in Rice 403
- Floryan's: M/Tu 1-2:30 in Rice 203
- Regularly scheduled office hours end this Tuesday, but there will be spontaneous ones (announced via the [Twitter announcement feed](https://twitter.com/@UVaCS2150))
- How is [Lab 12: Objective C](../../labs/lab12/index.html) going?
- The in-lab will take all of 5 minutes to complete; there is no post-lab
- Grading
- Grades through [Lab 9](../../labs/lab09/index.html) have been graded and returned; [lab 10](../../labs/lab10/index.html) should be back soon
- [Regrades](https://libra.cs.virginia.edu/~pedagogy/regrades.php) open for 10 days from the lab's return date
- The 10-day window will need to shorten as we approach the end of the semester
- Final exam info on the next slide
- Lectures are posted online in a Flash (ugh) movie format
- If they don't appear on the [uva/index.html](index.html) page, check the Resources section in Collab
- [Anonymous feedback](https://collab.its.virginia.edu/portal/site/41174582-53b0-472a-a22c-f466f2aa653a/tool/58a6dee4-eb97-4f29-9fab-9e6ad47e759d/main)! It's through Collab, and feeling lonely...
- [Readings](../../docs/readings.html) are optional, and are posted in the git repo
- Please fill out those course surveys!!!
- Today we will talk about [esoteric programming languages](../../slides/13-esoteric-pls.html) and the wrap up with the [course conclusion](course-conclusion.html)
</script></section>
<section data-markdown><script type="text/template">
## Final exam
- It's Thursday, May 9th, from 7 pm to 10 pm
- Yes, it's really late in the exam period -- we don't like it, either
- You can't take it early, so please don't ask
- You can ONLY take it late if:
- You have ALREADY notified us that you have a final exam conflict
- Or you have a religious exemption (if so, please let us know ASAP via a support request)
- In either case, we will get back to you in a week or so about the make-up details
- Location: Bloomfield's section is in the lecture classroom (Ruffner G005); both of Floryan's two sections are in Gilmer 130
- TAs will be holding various office hours before -- details will be on the [Twitter announcement feed](https://twitter.com/@UVaCS2150)
- There will be a review session prior; details to follow
- We *hope* to have it graded late the next day, but it may be very late the next day
- The final is cumulative, but with more of a focus on the material since the second midterm

## Final exam
- It's Thursday, May 9th, from 7 pm to 10 pm
- Yes, it's really late in the exam period -- we don't like it, either
- You can't take it early, so please don't ask
- You can ONLY take it late if:
- You have ALREADY notified us that you have a final exam conflict
- You have a religious exemption (if so, please let us know ASAP via a support request)
- In either case, we will get back to you in a week or so about the make-up details
- Location: it's in the lecture classrooms, but you have to go to the lecture classroom that you are acutally registered for
- There will be a review session prior; details to follow
- We *hope* to have it graded late the next day
- The final is cumulative, but with more of a focus on the material since the second midterm

- For the post-lab, we are currently thinking we will give a 1 day extension, but full details on Wednesday
- Regardless of the status of post-lab 9, pre-lab 10's due date won't be extended :-(
