What does it mean when a guy says he is proud of you?

My crush told me he is proud of me after I told him I got a good score on my mcat and he also told me he is proud of me when I got a honor roll award

Exact what it sounds like he is proud of you - A well done for your achievement

He is happy you achieved something difficult
