I wish people would talk about this, but Elon really isn’t that smart and he certainly isn’t a genius. I learned a long time ago that smart is relative and really shouldn’t be foisted onto people. Elon has a BA in Physics from a school known for business degrees. He also got a BS in Business, but UPenn and Wharton are known more for how hard it is to get in than how hard the classes are.
The website CollegeVine says UPenn is known as the “Social Ivy” and “UPenn’s admissions is highly-selective, but students applying to the UPenn College of Arts & Science (CAS) will find it less academically competitive than schools like Harvard, Yale, Princeton, and Stanford (although exceptional academics are still a must).”
By the way, he started college in 1990, transfered to UPenn in 1992, and states he graduated in 1995, but UPenn refutes that saying he graduated in 1997. This is a school where 96% of those who are accepted graduate within 150% of the degree time (4 year degree within 6 years) (https://www.collegetuitioncompare.com/edu/215062/university-of-pennsylvania/graduation/).
Musk of course says he completed the courses in 1995, but there was some sort of mixup with an English and History credit that delayed the degree by 2 years.
