COS 126 Exam 2 Information, Fall 2013


There will be a Q+A Tuesday night, December 10, starting at 8:30 PM in Friend 101.

The Tuesday-Wednesday precept before the exam will have time devoted to Q+A and review. The Thursday-Friday precept will be cancelled.

In order to compile a list of questions from past written exams that you would like to see answered, we will be using Google Moderator to prioritize your questions.

If you would like to bring up a question for discussion during the Q&A session, follow the link below. Either find the question you have and vote for it or, if you didn't find it, post it. (Finding your question and voting it up rather than just posting it anew is to your advantage, because repeating questions will steal votes from each other.)

Use a title format like "[Recursion] Fall 1978, Question 5B."


(You may also ask about review questions on Piazza or in office hours any time.)

Material covered.

The exam will cover all material in the course, but with an emphasis on the material covered after Exam 1:

The written part of the exam (in lecture) covers all of the above. It will be multiple-choice or short answer questions on the important material. The best way to prepare for this part of the exam is to read the book and the on-line packets, and study the lecture notes.

The programming part of the exam is strictly about programming. You will be asked to write a program from scratch (a mini programming assignment). Given the time limitation, this program will not be conceptually difficult, just a test of your ability to write a program that solves a simple problem. The best way to prepare for this part of the exam is to work a few of the easy exercises in the book and on the booksite that call for writing small programs.

List of topics.

This list is a summary of the main topics on the exam, for your use as a checklist when studying. Do you understand the basic ideas behind each of these topics? Do you know the names and contributions of the major players? If not, reread the appropriate sections in the book and lecture slides.
