You can use it to calculate your intelligence using this formula

let intelligenceScore; 
let actualHours = 10; // int
let listedHours = 300; // int
intelligenceScore = (listedHours - actualHours) / listedHours * 100;

console.log(`Congrats, your intelligence score is: ${intelligenceScore.toFixed(2)}%`);

Really, some sections may take longer or less time. Varies especially by user and previous experience. Believe it includes time spent working on projects, searching Google, reading docs, asking for help, etc. in addition to reading and solving each challenge.
