Try and keep your code DRY. You are using - Math.floor(Math.random() ); in 3 different places inside one function. maybe you can create a function?

if(randNum === 0){
let points = Math.floor(Math.random()*11);
student.score -= points;
console.log(`You have to work on ${subject}. I have to remove ${points} points from your score. You have only ${student.score} left.`)
} else if (randNum === 1 || randNum === 2) {
let points = Math.floor(Math.random()*11);
student.score += points;
console.log(`Great work on ${subject}. I add ${points} points to your score. You have now ${student.score} points.`);
}
}

}
