// when using && or || you need to do it like this
if (parseInt(answers) === 4 || parseInt(answers) === 3 ) { // notice the difference in this line :-)
  document.write('you won silver'); 
}

You don't need to use parseInt(answers) because you know it's an integer.

// else statements don't take arguments/conditions
else {
  document.write("None");
}

THIS IS NOT WORKING

var answers = 0;

var questionOne = prompt("What is the capital of India?"); if (questionOne.toUpperCase() === 'DELHI'){ answers+=1; }

var questionTwo = prompt("What is the national animal of India?"); if (questionTwo.toUpperCase() === 'TIGER'){ answers+=1;

}

var questionThree = prompt("Who is the PM of India?"); if (questionThree.toUpperCase() === 'NARENDRA MODI'){ answers+=1;

}

var questionFour = prompt("What is the national game of India?"); if (questionFour.toUpperCase() === 'HOCKEY'){ answers+=1;

}

var questionFive = prompt("Name of your country?"); if (questionFive.toUpperCase() === 'INDIA'){ answers+=1;

} document.write('Answers correct\n '+answers);

if (parseInt(answers) === 5){ document.write("Gold"); } else if(parseInt(answers) === 4 || parseInt(answers) === 3 ){ document.write ("Silver");}

else(parseInt(answers === 2) || parseInt(answers === 1)){ document.write("None");}
