At this point there is probably nothing you can do to complete the actual congressional nominations. For my son, I don't think any of them had info available online before May. Remember, they will want to see all your high school records (GPA, rank, etc.) through your junior year so that isn't available yet I'm assuming. Plus, you want to make sure that you include every activity, leadership position, etc. on your application--even things you do this spring and into the summer. There is no bonus for being the first to submit your application--they will all have a deadline for applications and won't do anything with them until that date. One thing you could start thinking about is who you may want to write letters of recommendations. Some MOC's want a school administrator, some want someone involved with an activity (like a coach), or just an adult that knows you very well. My son's also wanted a letter from a peer. Every MOC does it just a little differently--just be patient and be ready to go once their info is posted online!
