Guidelines

Full credit is possible only for problems whose complete, correct solutions are submitted before the end of your lab period. Be sure to submit what you have done before the period ends!

To ensure exam integrity, your screen will be recorded for the duration of the test and outside internet access will be cut off. You will still be able to access usna.edu and any USNA internal websites or services.

You can also use any written notes or books you bring with you, the course website, and any previous code from your own prior work in the class as references. (See Policy section below for full details.)

Before the day of the exam

Unfortunately because of the way the authentication works, you will not be able to login to the submit system web interface on the day of the exam.

To get around this limitation, you have two options:

• Use the club program. If you download and run this program at any time on any lab machine, then it will save your credentials and you can use this to submit and see test cases during your exam. (Just go to the project homepage and follow the instructions.)
• Use the submit script that you should have already downloaded. This will work, but you will not be able to see the auto-testing results which could be very helpful!

On the day of the exam

Open a terminal and run the following command:

/courses/roche/413/start-practicum

This should:

1. Confirm your name and that you're ready to begin
2. Start a screen recorder to help ensure exam integrity
3. Open a Google Chrome page where you can see the exam problems
4. Create a directory ~/413pract for you to do your work, and open a terminal tab for you in that directory

Inside the ~/413pract directory that gets created, you should find two files:

• exam.scm: Just contains "stubs" for the functions you are supposed to write for the exam. Write your solutions in this file.
• submitme.sh: A convenient shortcut to submit your exam.scm file to course "SI413" and project "pract".

Submission

There are 6 programming problems on the exam. Write your solutions to all of them in the same exam.scm file and submit as "SI413" project "pract". prior to the end of the exam period. You should be able to do this easily by running

./submitme.sh

from your ~/413pract directory.

Look at the auto-testing results. We will use the auto-tester to test your submissions, so make use of that feedback to make sure your code is running correctly!

If you encounter any issues, let your instructor know immediately.

Policy

• You may consult your own course notes, anything posted on the course website, and any of your own previous work from the class.

• You may NOT consult with any other human, including your classmates and anyone else except the instructor.

• You may NOT consult other internet sources not part of the course website

• You may NOT perform any internet searches or post questions or queries online.

• You may NOT discuss anything about this class or this exam with anyone that hasn’t taken it yet.

• You may NOT use your laptop or cell phone.

• You MUST follow good style practices for Scheme programming.

• You MUST ask your instructor if anything is unclear or there is a problem with submission.

Grading

With some exceptions, you will only get credit for solutions that compile and pass all or almost all of the auto-tests. Expect to get a zero for code that doesn't compile or mostly does not work. Do not spend all of your time on just one or two problems!!

The exam is only viewable with a valid token, which is associated to a particular student. These tokens will be sent out by email prior to the exam.
