A set is used to change a value therefore it also must recieve a new value of some kind. So you need one parameter for your method.

set major(name) {

}

If theres no parameter it should be a get method since it should return a value for you.

(Well actually you can change values with both Set and a Get but on a getter you dont recieve your change from a parameter).

Read the error provided by the editor

Bummer! Setter must have exactly one formal parameter.

This means that you must provide a parameter for the major setter
