I keep getting "Parse error" when I submit my work. I don't know how to check it to figure out what I'm missing.

Code is attached

script.js 
var isAdmin = false;
var isStudent = false;

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
} else (false) {
  alert ('Who are you?');
}

There is no need to pass in a parameter when using else.

if ( isAdmin ) {
    alert('Welcome administrator');
} else if (isStudent) {
    alert('Welcome student');
} else{
  alert ('Who are you?');
}

Thank you! Is that always the case? if and else if require (condition) and else does not?

Yup. Else is need no expression.

Yes, else in a way of speaking is you're fall back. "If" and "else if" need to have their conditions met to fire off the code between the curly braces.
