Math 330 Announcements and Q&A

Note that there is a Q&A section below the announcements!

1. Math 330 Announcements

12/22/2017 a. I rolled your letter grades into BU Brain last Tuesday. That's a manual process and errors are possible. Be sure to check your grade in your temporary transcripts and the one in BB!
b. I posted a new version 2017-12-21 of the MF doc. All content of the "Addenda to ch.nn" was moved to its proper spots, so now the references to theorems, definitions, equations, ... have been changed.
In the future there will be further improvements to this doc and you can access those from the Math 330 link for the new semester on my departmental page once that new web site is up and running.
12/15/2017 I corrected your BB grades: they were based on incorrect (too low) homework totals.
12/15/2017 a. Your final grade, total points (adjusted by +15 points) and letter grade are now on BB.
b. Congratulations are in order for almost everyone. You can be proud of your achievement in this tough course.
My best wishes for all of you! It was my pleasure to be your instructor. -- Michael Fochler --

2. Math 330 Q&A
This Q&A section is expected to grow over time.

Topic   Issue
Homework     Q: Are there some practice problems for the exams?
A: I started a document in July, 2017. I plan to add more problems. Here is the link for the sample problems .
Homework     Q: What is the significance of the "Due Date"?
A: Not much: If you submit your first draft earlier and if I feel like it I'll grade your work beforehand. If you submit your first and hence last draft at the last submission date I won't penalize you for waiting so long (other than having no more sumissions to improve your grade).
Homework     Q: Homework re-submissions: Do I need to redo every proof that was already correct or just the proofs that were unsatisfactory?
A: You only redo the problems that I did not mark as "done". If I tell you not to rewrite but provide some specific detail then you do so and you mark those additions with a different color (not red - that's reserved for me) color and indicate that you did so on your new submission.
Homework     Q: Homework re-submissions: Do I have to also submit the old drafts?
A: Yes: Staple the new one on the TOP of the older ones!
Homework     Q: What about the multiple reading due dates?
A: a. The staggered due dates for reading will help you to space out your work evenly so you won't fall behind.
b. You may be quizzed about the reading that was due by day n as early as on day n+1.
General     Q: I am a student with a disability/an athlete and need special accommodations.
A: Send me an email and bring the signed form (athletes: your coach or team director, Students with disabilities: see the syllabus, "Students with disabilities" paragraph) to me. I'll review this form before I sign it. If there are no issues I'll bring it to my next lecture.
If you have a disability, chances are that I want to talk to you in person to understand better how I can accommodate you, possibly in excess to what your form requests.
