If someone says congrats, the polite thing to do is to say,"Thank you".
You can just say "congratulations" you can get them a gift or do something special for them.
is it correct to say congrats the three of you
The appropriate thing to say when someone graduates is "Congratulations." You might also say "Good work" or "Nice job." They have worked hard for that graduation, and they deserve some recognition for it.
bravo
"Good Job" "Congrats" "Congradulations!" "Good Job" "Congrats" "Congradulations!"
"Congrats" is an abbreviation, not suitable for formal writing or polite discourse. You may say Congratulations to both of you, or -to you both.
Congratulation
Don't do it!
