Exam B -- Instructions

Exam B will take place as a remote exam on Thursday, 18 March 2021, at 17:00-20:00.

The set of instructions (1–9), which was posted for Exam A, applies also to Exam B (except that each instance of “ExamA” should be read as “ExamB”). In particular, a declaration form should be uploaded again if you did Exam A.

Independently of the above, please be advised that you need to register for Exam B via the Student's Services portal, according to the instructions found here.

Good luck!

Exam A -- Instructions (Part II)

  1. An assignment titled ExamA_Declaration is now open for you to upload your signed declaration form.
  2. Throughout the exam, you should be seen in two cameras — the smartphone's and the computer's — as shown in this video. However, contrary to what you see in the video, your computer is allowed to have only one screen.
  3. Once the exam starts, you are permitted to print the questionnaire within the first 5 minutes of the exam, as long as you are seen on camera while printing (this time is counted towards the total time of the exam).
  4. If you have questions during the exam, please inform the proctor (משגיח/ה) by raising your Zoom hand. You can then email your question to Ronny and Ramy, or ask the proctor to call us, in which case we will answer the question in a breakout room.

Good luck!

Exam A -- Preliminary instructions

Exam A will take place as a remote exam on Monday, 01 Feb 2021, at 17:00-20:00. Please read the following instructions early, as some of them require attention prior to the exam.
  1. Please read the Technion instructions for remote exams. These can be found under Course Material ⟶ Exam A – Instructions. Generally, they all apply to the exam in the course, with the exception of the use of Moodle; we will use WebCourse instead as explained in the next items. That link also contains a declaration form that needs to be printed and signed.
  2. An assignment titled ExamA_Declaration will be opened on WebCourse several days before the exam. Please upload your signed declaration form as a submission to that assignment no later than one hour before the exam starts.
  3. The (password protected) questionnaire of the exam will be available shortly before the exam under an assignment titled ExamA_Questionnaire. The password will be given out when the exam starts.
  4. At the end of the exam, you will upload the scans of the solution sheets to an assignment titled ExamA_Solution. In addition, for backup purposes, we ask that you email the scans to ucourse236309attechnion.ac.il.
  5. Hardcopy material (printed or written) is allowed during the exam. In addition, you may use e-copies of the textbook chapters and of your own submissions of the home assignments. The use of computing devices is otherwise disallowed, except for reading the questionnaire and for operating the Zoom connection.

We wish you good luck!
