Get StartedGet Starteda full class isn't full forever. seats open back up the whole registration cycle — the question is when, so you can actually be there for it. lemme put you on game twin. there are a few windows where seats drop way more than usual, and one daily fact that decides whether catching them is even possible. here's the real timing.
you can't catch a seat when the system's down. WebReg runs nearly around the clock but goes offline every night for maintenance, roughly 2 AM to 6 AM ET. outside that window it's live.
that's the part people forget. a seat can open at 6:05 AM the second WebReg comes back, or at 11 PM while you're asleep. the system is live ~20 hours a day — and you are not.
seats don't open evenly. a few windows produce far more movement than the rest of the semester combined:
find your semester's exact add/drop dates on the Rutgers academic calendar. that first week is the window where seats actually move — circle it.
people always ask if there's a magic hour. honestly — not really. a seat drops whenever the student who held it decides to drop, and that's scattered across the day. the one thing you can lean on is the moment WebReg comes back at 6 AM, since overnight changes post then. beyond that, "time of day" isn't a strategy. you can't predict the exact minute someone you've never met drops a class.
here's the honest takeaway. you can know every window on this page and still miss the seat, because the actual drop happens in a few seconds at a moment you can't predict — maybe during a lecture, maybe at 6 AM, maybe while you're asleep the third night of add/drop week. nobody can sit on WebReg 20 hours a day.
so the best "time" to catch a seat isn't a time at all — it's always on. that's the whole reason GhostReg, the Rutgers course sniper, exists. it watches your sections during every active WebReg hour, through all of add/drop week and beyond, and registers you the instant a real seat opens — first-week reshuffle, 6 AM reopen, random Tuesday, whenever. you don't have to guess the moment. you just get the confirmation email after it's already done.
