There is an appreciable boost by applying ED. But it won’t necessarily offset the GPA issue. So I’m not sure it will help applying ED to a school like Rice or Brown where you are unlikely to be accepted. But it will definitely help in schools like Baylor.
If you are premed, then just go to a school where you can get highest GPA possible. Going to a huge state U will make it difficult to stand out. Plus you can save money for med school. Chasing prestige as a premed is not worth it. Being an ORM, you will need a college GPA 3.8+ and MCAT 515+ to be competitive.
