Questions students ask

What is ChillSemester?

ChillSemester is a free planner for CUNY and Fordham students. It lists every class section at all 26 CUNY colleges (and Fordham's Rose Hill and Lincoln Center campuses), shows each professor's Chill Rank from Rate My Professors ratings, and builds conflict-free schedules ranked from Chill to Brutal. You never enroll through ChillSemester; you register yourself in CUNYfirst or Fordham's system.

Is ChillSemester free?

Planning is free with no card: browsing every class, professor ratings, building and stress-scoring schedules, saving one schedule, registration reminders and the degree audit planner. A one-time pass adds seat alerts and unlimited saved schedules: $6 for a Semester Pass or $10 for a Year Pass, with no subscription and no auto-renewal.

Where does the class and seat data come from, and how fresh is it?

Section times, rooms and seat status come from CUNY's public Global Search (Fordham's come from its public class search). A background job re-reads the catalog around the clock and each class page shows when its seat status was last confirmed. Seats can change between refreshes, so always confirm in CUNYfirst before you rely on a class.

How do I find out when a full class opens a seat?

Set a seat alert on the class (it comes with a pass). We re-check watched classes about every 2 minutes while that college's registration is open and about every 45 minutes the rest of the time, then email you if a seat opens. Alerts are best effort: another student can take the seat first and we cannot guarantee delivery.

What are the Chill Rank and the schedule stress score?

The Chill Rank rates one professor from 1 (Chill) to 5 (Brutal) by blending three Rate My Professors numbers: difficulty (50%), overall rating (25%) and would-take-again (25%), compared with other rated CUNY professors. A professor needs at least 3 ratings to get one. The schedule stress score rates a whole week from 1 to 5 using the shape of the week as well as the professors. Both are student opinion, not a measure of how good a professor is.

Does ChillSemester ask for my CUNYfirst login or register me for classes?

No. We never ask for your CUNYfirst password and never register for classes for you. You always enroll yourself.

When does registration open at my college?

It depends on the college and on your class standing. The registration dates page lists the dates each college has published, linked to its own source, and says so when a college has not posted one.

Can I send my schedule to a friend?

Yes. Any schedule has a Share button that gives you a link to copy, text or email. Your friend sees the classes, times and professor ratings without an account and can open the schedule in their own planner.
