Change Majors to Wharton?

Is it hard to switch majors into Wharton? This is if you apply as another major or undecided because I know Penn is known for their business program and is much more selective than other divisions in Penn.

It is possible for a Penn undergrad to internally transfer into Wharton, but it’s very competitive. See https://undergrad-inside.wharton.upenn.edu/internal-transfer/

@goodschoolbound it is more selective, but not MUCH more selective than other divisions at Penn. I always compare it to the difference in selectivity between Harvard vs Princeton for example. It is there but not a huge.
Internal transfer is competitive, but not extremely so. If you have a 3.4-3.5+ GPA freshman year and demonstrated interest in business then you have a good chance. Many people are successful in doing so.
