Defect Atmega board


My students blew up their Atmega board. What would be the odds do you guys think that replacing the Atmega will make the board working again? The Atmega has visible damage. (I have some experience with SMD Atmega328 soldering so that would not be the problem, but paying 5€ for a new chip and soldering for some time only to find kurt that more components are blown would be not nice ;)), one of the students told me they probably put 12V on some pin where they should not have done that.
