As stated on the syllabus: "Exams are open note: any printed or written material may be consulted during an exam. Electronic devices may be used only to consult the following: (i) e-books; (ii) resources on the class website. Electronic devices may not be used for any other purpose, unless stated otherwise in the exam. In particular, you may not write or compile any source code on an electronic device, and you may not perform web searches. A majority of exam questions will be similar to the sample exam questions provided on the course webpages."
Therefore, the best way to prepare for an exam is to ensure that you can effortlessly answer the sample exam questions. Note that solutions to all sample questions are provided on Moodle.
Exams will be 75 minutes in length.
