Need some quick help for PSA submission, stupid questions I know - I'm new to this

Ahhh, ok. I used to collect cards as a kid, but we're talking like Tom Henke cards in toploaders, or a 1990 score Sammy Sosa in a screw down case. Better yet, my crowned jewel as a kid: a Michael Jordan hologram card. SO SHINY! So ya, I've been back into it, now as an adult, for 3 1/2 months. I'm still a baby and am looking to learn as much as I can. I'm one of the young guns who will be in this world for a long time to come. I'm 25, but I'm sure there are plenty on here my age or younger.

Hey Shaun - I still don't understand if PSA grades trimmed cards or not. Some I see on eBay being sold with the PSA sticker: "EVID TRIM", yet others are obviously trimmed and get graded A. Why?
