Final Course Grades are posted

Hi everyone,

Course grades have been submitted to CUNYFirst, and a detailed gradesheet (including your final exam grade) has been posted on the GRADES page.  Let me know if you have any questions.

Happy holidays, and best wishes in your future work,
– Professor Reitz

Pre-Final Grades Posted

I’ve updated the gradesheet on the “Grades” page with all work submitted so far, including:

  • all 3 exams
  • all WeBWorK
  • all written work submitted so far (I’ll accept additional submissions in class on Tuesday)
  • all OpenLab work submitted so far (I’ll accept additional submissions through Tuesday evening)

NOTE: The “Course Average” column gives your grade out of 75 maximum.  Your final exam will INCREASE this by up to 25 points, giving you a final overall course grade out of 100.

NOTE: You’ll need the password to access the grades page – if you don’t remember it, send me an email.

Best regards,
Prof. Reitz

Exam Review 3 UPDATE

UDPATE 2 (11/5): The proof of #10 had a typo.
Near the end, after the line “Subtracting 504 from both sides”, the right side should end with a “-504” rather than “+504”.  Similarly, in the next line, the final parentheses should end with “-56” rather than “+56”.

UPDATE: The answer key has been added to the review sheet – let me know if you find an error!

Hi everyone,

Be aware, there was typo in problem number #9.  The left side of the equation should end in “n(n+2)” instead of “n(n+1)”.  Apologies for this error!

Office Hours today (11/14)

Hi everyone,

Today, I’ll be holding office hours from 12:30 – 2:00 (I will be coming from a meeting at 12:30 and may arrive a few minutes late).  However, I will remain in my office from 2:00 – 3:00 doing advisement, and I can continue to meet with students during this time provided advisement is quiet (if advisement is busy, I will need to focus on that).

For very quick questions, I’m available right after class for 10 minutes.

As always, you are welcome to post questions here or send them by email.


Mr. Reitz
