Should I contact Ivy Swim Coaches? Please Help!!!

Yes, keep in mind what @fleishmo6 says. If you want to look at some of the faster D3 schools, you will still need to make contact with those coaches. You want them to know you are interested because there are a lot of other swimmers out there with good times and strong academics. Once you have done the recruitment forms and established email contact, you can think of going on a visit with your family and meeting with the coach as part of the visit to the school. If the coach is seriously considering you for their team you will be invited for an overnight next fall. As well, you will most likely need to do that ED application.
