Help a college newbie out!

<p>Hello!
I have a few questions regarding course selection:
1) Why do some courses have no assigned instructor? Are they just waiting for it to become an official class (with a certain amount of people) or is it just undecided because of the professor's schedule.
2) If a course is listed, but there are no assigned instructor or date/time-then will my schedule be changed when they finally assign the time?</p>

<p>Thanks.</p>

<p>If there is no assigned professor, that means that he/she just hasnt been assigned to the class yet. The times are in stone so you wont have to worry about them changing the times on you. The TAs usually arent added until a week or 2 before classes start, if that.</p>

<p>One of the classes says “To be arranged” or something similar. But it’s good to know it won’t end up as something that conflicts with the rest of my classes.</p>

<p>TBA means there isnt a professor assigned right now but there will be later</p>
