Berkeley vs Boston University - Competitiveness

I’ve heard of big weeder classes and grade deflation at both schools.

Does anyone know which one is “tougher”? Thanks!

Should add: pertaining to mainly premed classes and big science classes.

UCB is well known for grade deflation and a tough school for premeds.

Both schools will have many intelligent, goal-directed, and driven pre-meds. It will be very competitive at both schools.
