Here’s a clear, professional, and friendly text you can use for (the CSUSM student portal) depending on what you need it for:

I had been a communications major at CSUSM, and I had loved every minute of it. My professors had been knowledgeable and supportive, and my fellow students had become like a second family to me. We had shared countless memories, from silly pranks to serious debates, and I knew that I would always treasure the time I spent here.

As I made my way through the campus, I saw familiar sights: the iconic University Hall, the bustling Student Union, and the tranquil botanical garden. I remembered late-night study sessions in the library, sunny days spent lounging on the quad, and countless hours spent exploring the nearby trails with friends.
