Challenges

Choose at least 3 out of the 5 points to complete in 45 minutes.

1. Create a Form for Course registrations that allows you to create a Course and its associated Teacher at the same time. Use a Form object approach to represent the Course Registration interface instead of nested params.
2. Add a Search bar to the Courses index that will allow searching by course name and subject. (Feel free to add gems as needed)
3. Set up a job to send students their grades when the course finishes (end_date). Consider that more than one course could end on the same date.
4. Create a form for Course metrics that will allow you to select a course, and submit and that will produce the following metrics: course grade average, top 5 students and failed students (less than a 70 grade).
5. Add a button to the Courses index named "Compute Grades". The button will schedule a job to calculate the average grades of each curse and send through a turbo broadcast update the index to show the average for each course.
