Here's how I did it, I added some of my own stuff for personal learning 

const quizQuestions = [
  ['What program are you studying?', 'Front End Development'],
  ['What is the name of your bootcamp?', 'Treehouse'],
  ['When should you be done with your curriculum?', 'Four Months']
];

  let correct = 0;
  let incorrect = 0;
  let right = [' '];
  let wrong = [' '];

for ( i = 0; i < quizQuestions.length; i++ ) {
  let userInput = prompt(`${quizQuestions[i][0]}`);

    if (userInput.toLowerCase().includes(`${quizQuestions[i][1].toLowerCase()}`)) {
    correct++;
    right += `<li>${quizQuestions[i][0].slice(0)}</li>`;

  } else if (!userInput.toLowerCase().includes(`${quizQuestions[i][1].toLowerCase()}`)) {
    incorrect++;
    wrong += `<li>${quizQuestions[i][0].slice(0)}</li>`;
  }       
}

document.querySelector('main').innerHTML = `
<h1>You answered <strong>${correct}</strong> correctly</h1>

<h2>You got these questions right:</h2>
   <ul> 
      ${right}
    </ul>

  <h2>You got ${incorrect} wrong:</h2>
    <ul> 
      ${wrong}
    </ul>
