UC Berkeley Bio-Engineering track and acceptance into medical school

My son has been accepted as regent scholar at UC Berkeley. He also has been accepted as USC Trustee scholar for full tuition. At UC Berkeley , he applied as BioEngineering and at USC he applied with intended major as Computer Engg. and CS with premed focus. USC will be a cheaper option [17k at USC vs 34k at UCB] but UC Berkeley is more reputable .

So, We are exploring both options and I would appreciate your response especially if you are a current student at UCB.

  1. I am very curious to know how many UC Berkeley BioE undergrads actually apply and get accepted to good medical schools.

  2. How difficult is to maintain high GPA in BioE at UCB to be able to get into medical schools? What is average GPA of BioE students ?

  3. He also is very strong at Maths and likes CS. In case, he later decides to pursue EECS or double major with EECS or minor EECS or L&S CS, what are his possibilities and chances? Will he have any priority to switch because he is regent scholar, if he keeps his GPA high.

Thanks for your time!
