I disagree with your premise, since our current situation is that different students in the same major _already_ end up in different levels of aptitude by the end of their studies. Some far exceed that of the typical student.
Preserve the ability for those with this level of prior experience or aptitude to thrive, while providing support for those who do not have this head start but could either (a) Catch up, given the right initial environment and ramp up, or (b) never catch up to the most well equipped students, but will still be proper graduates of the program.
