21-270: Final Exam Conflicts

Students who have a conflict with the final exam, scheduled for Thursday, May 9, from 8:30-11:30am in UC McConomy, can take a makeup exam. The makeup exam will be given on Monday, May 13, from 5:30-8:30 in MM A14. The makeup exam is the same time and place as the 21-240 Final Exam.

This exam is for students who have either a directly conflicting exam, or three exams beginning within a 25 hour period (one of them being the 21-241 exam). Students with a documented illness or University sponsored trip can also take the makeup. It is not a general alternate exam time.

21-260: Week #8 Solutions

I've posted the solutions to HW#8. You can find them on the "Solutions" page of the Blackboard site.

21-260: Exam #2 Review

Three of the problems listed from the textbook ought not to have been. Problems 7.1.2, 7.1.4 and 7.1.6 all deal with second order differential equations, which we have not yet covered. You can safely ignore them. Also, I will hold a review session this evening from 6:30-8:00 in PH 100.

Exam #2 Review Problems

I've added another large collection of review problems to the exam review page linked from the Schedule page. Also, be sure to look at the homework solutions posted on the Blackboard site.

21-260: Exam Strategy

I just responded to a student email asking about studying for the exam, and what type of exam you can expect. This is what I wrote:

I would say that working through practice problems is the best way to prepare. You should also review your class notes, and especially your graded homework. When you are working problems, keep track of things you need to look up or ask about. Those are things you should focus on as the exam date gets closer (as it is now!)

On the day of the exam, I would recommend taking a couple minutes to read over the whole exam. Sort out which problems look easy, and which look more challenging. Finish the easiest problems first, leaving you more time to think about the harder problems without distractions.

Regarding the makeup of the exam. You can expect 20-25% of the exam to be pretty straightforward, and another 20-25% to be pretty challenging. The rest somewhere in between. There will be some conceptual material, like on the written homeworks, but most of the exam will be more computational.

21-260: Exam Odds and Ends

As announced in class today, our first midterm is this Wednesday from 7:30-8:20 in UC McConomy. There will be no class on Wednesday. I will hold a review session tonight from 6:30-8:00 in PH 100.

I've added "Systems of Differential Equations (Section 7.1)" to the list of topics covered. That is what I've been telling people all along, but I inadvertently left it off the list. I also added 7.1.23 to the practice problems from the text.

21-260: Week #14

The reading and homework assignments for Week #14 have been posted, as has the Exam #3 review page. You can follow the links from the Schedlue page.

21-260: Exam #2

Most of you should have your Exam #2's back by now. The grade cutoffs for the second midterm are: A - 80, B - 70, C - 60, D - 40. If you took the makeup exam on Tuesday morning, I have your graded exam, you can get it before or after class tomorrow. I've made the grades available on the Blackboard site.

21-260: Exam Date Changes

As I announced in class yesterday, I've had to move the second and third mid-term exams from their originally scheduled dates. The second mid-term, instead of being the Wednesday after spring break, will be the Friday after spring break, March 23. The third exam, instead of the Monday before spring carnival, will be the Friday after spring carnival, April 27.

I think the new dates will be generally preferable to the original dates, but in case they are not, let me tell you that the alternative would have been to give the exams on the scheduled days at 7:30 in the morning.

21-260: Exam #1

I returned Exam #1 during class yesterday. If you didn't get yours, you can pick it up from your TA during recitation today. The grade cutoffs for the exam are - A:85, B:75, C:65, D:50. These cutoffs are important for two reasons. First, it gives you an idea where you stand, and second, I use them to compute grade cutoffs for your cumulative averages.

Since the grade cutoffs for this exam are the same as for the homework assignments, the grade cutoffs for cumulative averages are the same, too - A:85, B:75, C:65, D:50. I compute the grade cutoffs for cumulative averages by averaging the grade cutoffs the same way I average your grades (i.e. the A cutoff for cumulative averages is the average of the A cutoffs for each assignment).

An important point to note is that, when computing your averages, the difference between, say, an 84 and 85 is only a 1% difference, not a whole letter-grade difference.

I will make your exam grades and cumulative averages available on the blackboard site.

21-122: Final Exam

The final exam has been scheduled; it's not particularly good news. Our exam is scheduled for Tuesday, December 20, from 8:30-11:30am. You should check the schedule to see if you have any conflicts among your exams. If you have three exams starting within 25 hours, your are also entitled to some relief. I will not offer the exam at an earlier time, but I can schedule a makeup exam later in the day if necessary to resolve conflicts.

The Exam #1 review is now posted *and* linked from the schedule page.
