There will be no Week-in-Review the week after an exam.

There are multiple ways to break the ties that you asked about in WIR
(fipping a coin, giving the first tie to the first person and the second
tie to the second person, starting with the tied item with more points, etc.).
Unfortunately, the computer did not use a single one consistently.
If you lost points on a multiple tie question, talk to your teacher.
