I'm gonna be honest with you, I don't really keep track of cooking time.
First I get the water bubbling hot, then I add the seasoning packets and noodles. After the noodles begin to separate, I drop in two eggs. Be sure to stir them right after you do to prevent parts of them from sticking to the bottom of the pot and becoming a gigantic bomb in the rear to clean off.
Dorm cooking isn't an exact science unless you make it one. So long as the egg white is cooked through, you should be fine.
I have tried soft boiling eggs before, didn't go so well the first time. Be sure you boil the eggs for at least 6 minutes and immediately shock them in an ice bath.
