i dont know what i am doing wrong?

I'm assuming you finished the first task?? If so...

Task 2/3: Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop.

I have redone this challenge just now and I found that the while condition requires you to check if it IS equal to No, and No exactly. Also, you didn't JUST declare response outside the do-while loop, you assigned it also, don't do that for this task :). So just declare it.

Here is what your code should look like for task 2/3:

String response;
do{
  response = console.readLine("Do you understand do while loops?");
} while(response == "No");        //make sure that No is capitalized

Now for task 3/3: Finally, using console.printf print out a formatted string that says "Because you said <response>, you passed the test!"

All you want to do is go outside the do-while loop and print "Because you said <response>, you passed the test!". Make sure you do this OUTSIDE the do-while loop:

String response;
do{
  response = console.readLine("Do you understand do while loops?");
} while(response == "No");
console.printf("Because you said %s, you passed the test!", response);
