= is assignment. comparison is ==, but you shouldn't use == here. see here for fuller explanation. If you haven't covered objects yet, then maybe worry about the difference between == and .equals later. It is something you should know about at some point when learning java.

The complete code for that challenge is

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