Improved Personal Deck Assignments

We updated Personal Deck Assignments to be more focused on promoting consistent studying. Here's how the improved Personal Deck Assignments now work:

1. Teachers set a target number of points for students to reach.

2. Teachers then set a due date, and students have until that date to reach the target number of points.

Students earn points by completing a personal deck study session. The first session of the day is worth 1 point, while any subsequent sessions that day are worth 0.5 points. Because the first session of the day is worth more, students should prioritize completing one session per day, rather than cramming all of the study sessions into one day.

In the screenshot below, this student has completed the first study session of today, so the student has so far earned 1 point. The student needs 1 more point to reach the target of 2 points, so the student should log back in the next day and complete another study session:
