FAQ

I missed (or will miss) a Tutorial session, examlet, or homework - what do I do?

I am in lecture section AL1/AL2/BL1/BL2/CL1/CL2 - is this my website, and what do you mean by sections "A", "B", and "C"?

All sections of this course run in sync and use this website. We refer to both AL1 and AL2 as section A (9:30 meeting time), and sections B and C are defined similarly.

PrairieLearn seems to be unenrolling me, or giving me weird access errors!

You are probably in CS 128, which uses a separate PrairieLearn login. So log in again with your standard UIUC credentials (either in a different browser or after logging out of your 128 account).

Which building is "Siebel"?

If we ever forget to specify, we're talking about Siebel Center for Computer Science, not Siebel Center for Design.

Regrades / broken questions

We try to write questions with no errors and to grade with perfect accuracy. But, of course, we are only human. Mistakes happen and need to be corrected.

I haven't submitted the problem yet, but it's clearly self-contradictory (or otherwise broken)!

While our questions are sometimes broken, the vast majority of the time the question's fine and you are misreading it. It's not too late to figure out what it really means and get it right! Read it again, and make sure you're spending at least as much effort trying to figure out how you could be wrong as you spend trying to explain to us why we're wrong. (Though sometimes the latter is a good way to do the former - write out very explicitly why we're wrong, and then review your argument critically, looking for the weakest point.) If you still think it's wrong and it's a homework question, talk to us in office hours or Piazza; if it's an examlet, then take your best guess.

I submitted the problem, and disagree with the grade I received (either the grading or the question seems wrong).

First look over the given solution and try to figure out on your own what went wrong. If our solution doesn't make sense, talk to us at office hours rather than submitting a regrade request. If after the previous steps you want to submit a regrade request, go to the question on PrairieLearn and click the "Report an error in this question" button. If the issue is with your grade rather than with the question, include the text "Regrade request:" as the first words of your report. Regrade requests might not be considered if submitted beyond one week from when we post grades for the assignment.

Curving / letter grade cutoffs / extra credit

See this page. In particular,

Is an 87% enough for a B+? (etc)

We do not guarantee any thresholds in advance other than the ones linked above.

Is the course curved?

This is the same question as the one above.

Are individual assignments curved?

No.

Is there extra credit?

No.

Are grades rounded, e.g. is a 79.5 or a 79.95 the same as an 80?
