So how is 3rd year set up here? In the curriculum hand-out, they did post the required rotations...do you get a chance to add electives? When they say 9h vs 4h, does that mean 9 weeks vs 4 weeks? Do you have to find electives yourself or do they offer them and you can choose? During rotations, are you rotating with just RFU students or also RFU/Rush/UIC/etc students?
Everyone does the required rotations 3rd year- no electives. That is what 4th year is for, though, and you will have plenty of time. Also, for instance if you are interested in your child neuro, during your peds rotation you can ask to go hang out with the child neuro people for a while. It usually works out.
As for the handout, the 9h/4h are credit hours. The rotations are actually 8 weeks, 6 weeks, or 4 weeks.
As for electives, there are intramural and extramural. Intramural electives are at hospitals affiliated with the school. The rotations are set up, and there is an internal app service. Extramurals are anywhere in the world, and they are usually already set up as well (though you can always make a new one).
During rotations, you are with different groups for different rotations. Almost all of the time, you are with UIC, Midwestern, and some Northwestern as well.
