Put the concept of specific degree from specific university equals X amount of money out of your head. It doesn't work like that. You first need to get your degree, then be able to show to relevant interests and experience within the field you are applying in addition to actually getting through what usually is a highly convoluted application process. If you set out to expect 25k when you graduate it will be a lot easier for yourself, as opposed to setting a highly unrealistic target, only achieved from highly lucrative, extremely competitive positions. Remember that even if you start at 25k, that doesnt mean your salary couldnt rapidly increase within the first couple of years.
Good job and good salary = Degree X from uni Y + hard skills + soft skills + experience + interests + determination + luck
not
Good job and good salary = Degree X from uni Y
