This page contains the information about when and where exams are held, topics covereds, review sessions, extra office hours, and more.

Final Exam Info: Final grades are ready!

Here are some reminders about the final exam, review sessions, and topics. Keep checking this newsgroup for any further announcements between now and the final exam.

Sample solutions to the last assignment will be available in Carpenter beginning Thursday afternoon, Dec. 4.

Some consulting will be available during study week. Unclaimed work can be picked up then. The schedule will be posted here once it is final.

Grades will be posted after the final assignment is graded and all regrades we are aware of have been processed. An announcement will be posted here when grades are available. Once they are, you should check our records and notify Laurie Buck (the course administrator) of any errors.

The final exam is Monday, Dec. 15, 3:00 pm in Barton Hall Center (middle third of the room).

Review Session(s):

Tue., Dec. 9, 2pm, room Phillips 101: loops and invariants.
Sun., Dec. 14, 3pm, Olin 155: anything.

Extra consulting hours for study week:

1-4pm Monday - Saturday

Final exam topics: The final exam for CS100A will be comprehensive, including material from all three prelims as well as anything covered since then. This list includes new topics covered since the third prelim. You should review the topics covered on the earlier exams in addition to the new material here.

New material since the last prelim:

C programming. You should be able to read a short C program, trace its execution, decide what it prints, answer questions about how it works or what it does. In particular, know how pointers are used as parameters, the & and * operators, the meaning of types like "int *" in parameter lists, arrays, structures (struct) and typedefs to define struct types, and the use of structures and arrays as parameters. Be sure to understand the difference between array variable names used as parameters vs. variable names of other types. You will not be expected to write any C code. You also don't need to understand the format codes ("%d %.1f%", etc.) found in printf statements, but you do need to know that printf prints the value(s) of its parameter(s).

Internet. You should understand the basic concepts covered in lecture 24 and know the basic vocabulary. Concepts:

packet switching
WANs and LANs; how they are connected to form the Internet
client-server computing
the rolls of TCP and IP; how they interact with each other, applications, and hardware
internet addresses and computer names; the role of domain name servers (DNS)

You do not need to memorize lists of acronyms like nntp/smtp/http, nor do you have to know what they mean.
