Questions & Answers about Ustedes se han graduado y tienen una oportunidad excelente.
Why is there a se before han graduado?
The verb for "to graduate" is reflexive in Spanish: graduarse. When using the present perfect tense, reflexive pronouns like se must go immediately before the conjugated form of haber (in this case, han). You can never put a word between haber and the past participle.
Since Ustedes is plural, why doesn't the past participle change to graduados?
When a past participle (like graduado) is used with the helping verb haber to form the present perfect tense, it never changes its ending. It will always end in -o, regardless of whether the subject is masculine, feminine, singular, or plural.
Why use han instead of another form of haber?
Han is the present tense form of haber used for ellos, ellas, and ustedes. Since the subject here is Ustedes (plural "you"), you use han along with the past participle graduado to mean "you all have graduated."
