examtool 2.2.45

No project description provided

Overview

This is the CLI for the 61A examtool. To edit the various web apps, see the other exam-* folders in the cs61a-apps repo.

To install, run pip install examtool[cli]. To develop, create a virtualenv and run pip install -e .[cli].

The CLI also requires wget and pdflatex to be installed and in your PATH.

To deploy exams to the server, you must be registered as an admin for your course at https://auth.apps.cs61a.org.

Workflow

First, visit https://write.final.cs61a.org to write your exam, following these instructions. When your exam is ready, export it as a JSON and place the JSON in a folder.

In that folder, run examtool deploy and select that JSON along with a roster CSV. When deployed, the exam will be accessible at https://exam.cs61a.org. Roster CSVs must have a header and the columns:

• Email - The email of a student
• Deadline - The due date of an exam for a particular student expressed as a Unix timestamp
• No Watermark - An optional column that is 1 if this student should not receive a watermarked exam (e.g. for DSP accomodations). Defaults to 0 if not specified.

You may wish to send exam PDFs to your students. To do so, run examtool compile-all to generate unique encrypted PDFs for each student. When they are all generated, run examtool send to email them to your students. Note that compilation requires pdflatex and wget. Compilation of watermarked PDFs also requires inkscape.

After your exam ends, run examtool download to download your student submissions as a single CSV and as PDFs to upload to Gradescope. To upload them to Gradescope, run examtool gradescope-upload.

To use an experimental autograder, run gradescope-autograde to download the exam, create the Gradescope assignment, upload them to Gradescope, add the outline to Gradescope, group all of the submissions, and finally apply grades to the groupings! Note you can use the same command to upload and autograde exams to the same Gradescope assignment, just ensure you use the update flag.

If you do not want the exam to be autograded, run examtool download to download your student submissions as a single CSV and as PDFs to upload to Gradescope. Use the --via-html flag to create formatted PDFs, or --direct-pdf to create plaintext PDFs. You must install wkhtmltopdf and place it in your PATH to create formatted PDFs. You can also use the experimental flag --via-latex to embed student responses in the printable LaTeX PDF.

To upload PDFs to Gradescope, run examtool gradescope-upload.

Note that if you ran alternate versions of your exam, it is possible that a student might have taken both versions (say, if they switched from the regular to the alternate version after filling out part of the regular version). To check for such students, run examtool check-dupes, and then manually decide which of their submissions should be uploaded to Gradescope.

Run examtool loginas to log in as a student and view their exam.

To identify cheating or recover from students losing their Internet connection, run examtool logs to see the full submission history of a particular student, or all students in the roster.

Run examtool save-logs and then examtool cheaters to identify students who have used substituted words that did not occur in their exam, implying that they may be cheaters. Run examtool identify-watermark if you have a screenshot of a watermarked exam that you wish to identify. Run examtool identify-keyword if you wish to determine which students received exams with a particular keyword.
