I got my acceptance the Georgia Tech on Tuesday. Checking the status is confusing because in the Application Status section it still says "Pending Department Review", but right above the Online Letters of Recommendation section there is a button that says "View your decision letter" Also, I received an email a couple of hours before the decision letter was available telling me to check the website after a certain time. Hope this helps!
I didn't apply to UCSD or Brown, so I can't really say anything about them
