Nobody remembers who got credit on the group project. They remember who actually did the work.

Credit gets assigned quickly and forgotten just as quickly, while the knowledge of who carried something stays with everyone who was in the room. That knowledge shapes who gets asked next time, which matters far more than whose name went on the front. Attribution is loud and short lived.

Do the work well and stop fighting for acknowledgement, because the people whose opinion affects your life already know. Keep a private record of what you did if it helps. Then let the visible credit fall wherever it falls.
