Math 21b - Exams

Course head: Janet Chen
Course preceptor: Yu-Wen Hsu (yuwenhsu@g.harvard.edu)

Out of sequence exams are only offered for the following reasons:

Out of sequence exams will only be given before the actual exam.

Exam 2

Exam 2 will be Tuesday 11/14, 5:30 - 7:30 pm in Science Center C. If you have a valid conflict (see the top of this page), please fill out this exam conflict form by Wednesday 11/8 to arrange an earlier exam time. Please note that most sections and labs can be rearranged to accomodate an exam, and we expect you to contact your section organizers right away to arrange to attend a different section if your section conflicts with the 21b exam.

What to Expect

The exam will focus on the material on Problem Sets 12 - 27, but it is cumulative in the sense that this material relies on the ideas and techniques from Problem Sets 0 - 11, so you will still need to be comfortable with those. Remember that Math 21b emphasizes deep and flexible understanding of the material. As such, you should expect the exam to include problems you haven't previously encountered, so that you can demonstrate your ability to apply the fundamental concepts to new problems.

Books, calculators, and notes will not be permitted on the exam.

How to Study

We encourage you to start studying early by reviewing your notes, worksheets, and homework to help you recall the key definitions, skills, and concepts we've covered so far. Make a list of important definitions, ideas, and strategies for yourself, and explain to yourself why the strategies work. Here is some material that may help you with this review:

The single best thing you can do after this is to complete a few practice exams without looking at the solutions or using extra aids. (It is very tempting to peek at the solutions when you get stuck, but we have found repeatedly that this is not a useful study strategy. Recent research backs this up!) After you've finished a practice exam, don't look at the solutions yet! Instead, go back to any problems you weren't able to do, and try them again, using any source you like except the solutions (so, for example, look for related problems from the worksheets and homework). Finally, after you've done that, look at the solutions and grade your work, and go to office hours with any questions you have!

Review Session

There will be a course-wide review session Thursday 11/9, 2:45 - 4:15 pm in Science Center E. We've asked for the review session to be taped.

How to Study

We encourage you to start by reviewing your notes, worksheets, and homework to help you recall the key definitions, skills, and concepts we've covered so far. Make a list of important definitions, ideas, and strategies for yourself, and talk over your list with other students.

Here is review material; the 4 practice exams are formatted in the same style as your exam will be, but the past exams are also excellent sources of problems.

Review Session

There will be a course-wide review session Friday 9/29, 2:30 - 4 pm in Science Center A. We have asked for the review session to be taped.
