We plan to have the week long test phase of the challenge between Nov. 15, 2021 and Dec. 15, 2021. Which of the weeks will work well for your time? Please select all that are convenient considering your exams and/or other commitments. We will choose the test phase based on what works for most participating teams. [Disclaimer: While we will try to cater to most participants, unfortunately, there is no way to guarantee that all your choices will be met.] *
