Exam conditions

The timer starts when you press Start quiz. The questions appear only then.
Each attempt uses 30 random questions from a bank of 70, so every try is different.
When the 20 minutes end, the quiz locks and your score appears. You can also finish early.
After checking you get feedback in English and Spanish for every answer.

Who Object Vs. Who Subject

Subject questions

The question word is the subject: no do/does/did. Question word + verb

Who called you? (Anna called me.)
What happened? · Who lives here?

Object questions

The question word is the object: use an auxiliary. Question word + auxiliary + subject + verb

Who did you call? (I called Anna.)
Who are you waiting for? · What did she buy?

Compare

Subject question	Object question
Who saw Tom?	Who did Tom see?
Who loves Maria?	Who does Maria love?
What broke the glass?	What did he break?

Watch out

Subject questions: past simple stays without did: ~~Who did call you?~~ → Who called you?
Whom is the formal object form; in speech we use who. Formal: To whom did you speak? Informal: Who did you speak to?

En español

Si who/what es el sujeto, no se usa auxiliar (Who called you?). Si es el objeto, sí (Who did you call?). Whom es la forma formal de objeto.
