Yeah this is often a tough break for students who see their LSAC gpa for the first time. You have to just accept your splitter status and move forward by killing the LSAT.
Hmmm that's weird. You can email Northwestern about it, but I think you should get a new password by going to their page and clicking "Forgot Password?" https://www.law.northwestern.edu/admissions/status/
Definitely JUST wait. Do not email, call or check on your status. Don't ask if they rank the waitlist. Schools often will update you so it's a "don't call us, we will call you" situation. Good luck.
