<p>Most courses meet 3 “hours” a week. Technically they meet either 50 minutes 3 times a week, or 75 minutes 2 times a week. Both obviously total 150 minutes of class time. So that is called a 3 Hour, or 3 Credit, or 3 Credit-Hour, course. You will see all these terms and they are interchangeable. Now while most fall into this paradigm, you cannot take it completely literally. There are courses that meet 4+ hours a week but are still considered a 3 credit-hour course. For example you might meet in class 3 hours and then have a 2-3 hours film session in the evening once a week, if that is pertinent to the course. But most common by far is that you have a history class that meets, for example, MWF from 9:00-9:50, while your English class meets TR (R=Thursday) from 1:00-2:15. You might also be taking Introductory Spanish, which meets MWF 10:00-10:50 and T from 9:30-10:45, and that is considered a 4 credit-hour course.</p>
<p>The general thinking is that most students are going to get one degree and therefore have to complete 120 credit-hours of coursework. That averages 15 hours, or 5 courses of 3 credit-hours each. That is considered a normal load, although as few as 12 will still maintain your status as a full time student. You cannot take less than 12 hours a semester and still be full time, normally, and your scholarship requires that you maintain full time status. So as I said, with 19 hours in a semester, you would be taking six classes of which one would have to be a 4 hour course. Also, know that labs are never counted for as many hours as they actually require your physical presence in the lab. So for example the 1 credit-hour General Chemistry lab course that goes with the 3 hour Intro Chem course actually requires 3 hours a week of being in the lab.</p>
<p>This may seem complicated, but you will quickly get used to it. It is much harder for science majors to load up because those lab courses block a lot of scheduling. So for example if your Chem Lab is 12:00-3:00 on Tuesdays, you cannot take any courses offered on TR that overlaps with that.</p>
<p>I think that covers it, but if I have left anything unclear, get back to us and I or someone else will clear it up. This is standard at most US universities, so most of us are very familiar with it. It is not at all unique to Tulane. In fact when I was at Tulane they used a different system, not sure when they changed. But there is a great story of something I went through because of that old system, but too long to post I think.</p>
<p>Have you looked at the course offerings yet? They give the credit-hours and meeting times assiciated with each course. You should start looking for classes you think you might want to take and start working out a schedule. The site has a nice Planner tab that shows your course blocks as you start choosing. You can play with it without fear, it doesn’t actually sign you up until you log in and are ready to do that for real. <a href=“http://classschedule.tulane.edu/flex/ClassSchedule.html[/url]”>Tulane University Schedule of Classes;
