I sent a combined letter of update and interest to all of my schools in late November. I've been recently waitlisted by a few of my top choices and I want to send these schools another letter of interest, but how can I do so without saying the exact same things? Unfortunately, I do not have any updates this time since I've been taking second semester extremely lightly. Should I simply reword my original letter and send a short paragraph to these schools expressing why I still want to attend (without any updates)? I feel like not sending anything definitely will not help me get off the waitlists.
