I've found that you get a lot better information just by reading a school's web site. Read it over and over because, face it, JW's are out of the loop as far as terminology and usage; what the school means and what those out of the loop think it means are often very far apart.
If you have questions about something on the site do this: First, read and read again. Second, find an email address for the department responsible for that section of the site (Admissions, Records, etc.) then email your questions or concerns. It's better to have a written record of interactions; you can go back over it again and again until everything gels.
As far as campus tours, do it on your own a time or two (or three...). Visit at different times of day and different days of the week, just as you would if you were scouting out a new neighborhood in which to live. It may be difficult distancewise or timewise, true, but if you are planning to spend a significant amount of time in their environment it's well worth it. There's always a campus map online, print it and take it with you. Find the on-campus eateries, spend some coffee time there and listed/watch. Visit the Library. Hang around or walk around leisurely, you'll find people to talk to, a question here and there. That and your own silent observations are worth more than the guided tours.
Check out RateMyProfessors.com. Plug in the names of the instructors for the various classes you are interested in and get some advance warning on what to expect. You can match names to classes using the college catalog and schedule of classes.
Go to YouTube.com and search for videos by your prospective school...and it's clubs and individual students. If it's a college town then search out the local newspaper vids to get a feel for the relations between the townies and the students.
Not trying to sound tough here, but....the whole entrance process is a screening mechanism in itself. They're not really going to hold your hand no matter how much they say so online or in person. You have to navigate pretty much on your own. Them that can makes it and them that can't doesn't. That's hard on people who haven't been exposed to the whole higher education thing through their families or other support groups but hey....we made it this far, we can do the school thing too. It's just going to be a bit more stressful than for some.
Been there, did that, made it through just fine.
