<p>What are the differences between them? I looked them up on the Course Synopsis and the descriptions are virtually the same…</p>
<p>I believe the 001 course is the lecture, and then the 01-D (or 02-D, 03-D, etc) is the discussion section. In a class like ECON 51 you need to register for both the lecture and a discussion section.</p>
<p>What about language courses? I’m planning to take Intermediate Japanese. Do I have to register for both 001 and 01-D?</p>
<p>For that particular course it looks like the lecture (001) is required and the discussion (01-D, 02-D, etc.) is optional. </p>
<p>You probably want to look at the [Schedule</a> of Courses](<a href=“http://soc.siss.duke.edu/psp/PS090SOC/EMPLOYEE/HRMS/c/DU_SELFSERVICE.DU_SRCH_SUBJ_STAFF.GBL?PORTALPARAM_PTCNAV=DU_SRCH_SUBJ_STAFF&EOPP.SCNode=HRMS&EOPP.SCPortal=EMPLOYEE&EOPP.SCName=DU_PUBLIC_SCHEDULECATALOG_VIE&EOPP.SCLabel=Public%20Schedule%2FCatalog%20View&EOPP.SCPTcname=DU_SC_SP_PUBLIC_SCHEDULECATAL&FolderPath=PORTAL_ROOT_OBJECT.PORTAL_BASE_DATA.CO_NAVIGATION_COLLECTIONS.DU_PUBLIC_SCHEDULECATALOG_VIE.DU_S200901121424114840540787&IsFolder=false]Schedule”>http://soc.siss.duke.edu/psp/PS090SOC/EMPLOYEE/HRMS/c/DU_SELFSERVICE.DU_SRCH_SUBJ_STAFF.GBL?PORTALPARAM_PTCNAV=DU_SRCH_SUBJ_STAFF&EOPP.SCNode=HRMS&EOPP.SCPortal=EMPLOYEE&EOPP.SCName=DU_PUBLIC_SCHEDULECATALOG_VIE&EOPP.SCLabel=Public%20Schedule%2FCatalog%20View&EOPP.SCPTcname=DU_SC_SP_PUBLIC_SCHEDULECATAL&FolderPath=PORTAL_ROOT_OBJECT.PORTAL_BASE_DATA.CO_NAVIGATION_COLLECTIONS.DU_PUBLIC_SCHEDULECATALOG_VIE.DU_S200901121424114840540787&IsFolder=false) rather than the Course Synopsis Handbook. Make sure to select Fall 2009 for the term from the drop-down menu. Once you select a subject and class, click on any particular section. Under “Class Components” in Class Details, it should show you if the discussion/lecture/lab is required or optional. </p>
<p>The Schedule of Courses is also nice because it shows how many spots are still open for any given course. Since upperclassmen have already started to register, it allows us incoming freshman to get a feel for which classes are still going to be available when our registration windows open. Many classes also have the professor assigned to them already, so you can do a little ratemyprofessors.com research ;)</p>
