<p>1) If you’re leaning towards explorations floors, go wherever that is. I lived on one my freshman year, and I’m still friends with a lot of the people from my floor. However, I was never really a fan of Rubin because it’s kind of out in the middle of nowhere compared to the other dorms and the dining hall there kind of sucks (it’s been three years since I’ve eaten there though, so maybe it’s improved).</p>
<p>I lived in Brittany (pre-renovations) and I really liked the location and it actually has AC now! I liked the proximity to Union Square (way more fun than Washington Square IMO), Founders, and the dining halls at Palladium and 3rd North. Founders is also pretty nice, and again, is nicely located. I’m not a huge fan of 3rd North mostly because the rooms are pretty small and because I don’t think I would have ever left the building if I had a dining hall immediately downstairs 
UHall is great for proximity to dining halls, Union Square, Trader Joe’s and is right next door to Palladium, but again, rooms are not that big.</p>
<p>TL;DR: my favorites were Brittany and Founders, obviously you may have different priorities.</p>
<p>****Ask for a double. So much better than more people. I lived in a 5 person walk through suite freshman year (3 people in one room, 2 in the other, but you had to walk through the 3 person room to get to the 2 person one) and it was a nightmare. Learn from my mistakes, doubles are much much better.</p>
<p>Class enrollment - you do it when you go to orientation. Basically how it works is that they reserve a certain number of spaces in each big intro/core class for each orientation session. At orientation, you take placement tests for languages, math, science (if you’re trying to get into honors chemistry only), and then once you get the results from those, you know what classes you can take. During orientation, you get divided into groups with a group leader who helps coordinate registration. Basically, they’ll help you figure out what classes you need and help you register for them at your designated time. It’s pretty hectic, and classes tend to fill up pretty fast, but it generally works out fine. After registration, you can move classes around on your own time on Albert if there are other openings or you want to change classes</p>
