This is totally school-specific, so you should ask the clinical coordinator at your school like the previous poster suggested. Some schools allow students to take electives (or even sub-Is) during third year, while others don't. Some schools don't even require sub-Is, while others require two or three of them. So you really need to ask someone who is knowledgeable about the curriculum at your specific school. Best of luck.HOw many electives are u allowed to take in 3rd year, outside of the required clerkships?
How many electives/sub-internships/away rotations are allowed in 3rd and 4th year?
Don't know exactly what the op wanted, but I'd be interested in hearing about how much elective time during 3rd year people have at different schools. You can't really judge one school's curriculum without knowing how others do it.
