Challenge: Student Course Scoreboard

You have seen the pattern in the demo. Now write the program yourself in script.js. Keep the focus on values, conditions, loops, arrays, or functions—not page elements.

Worked example

For a different collection, read every value rather than hard-coding a position:

const miles = [2, 4, 6];
let total = 0;
for (const mile of miles) total += mile;
console.log(total / miles.length); // 4

Checkpoint

Run your code after each small change. The Console should show one clear summary once all checks pass.
