Screen Description
There are two kinds of the Course Reservations screen  one of them for course reservations on an instructional offering, the other one for course reservations on a class.
Details
For each course reservation, there is the course title for the controlling course in that instructional offering displayed in the upper part of the screen. A table follows.
Course Reservations  Instructional Offerings
The table for course reservations on an instructional offering is essentially the same as in the Instructional Offering Cross Lists screen. You need to indicate the number of reserved spaces for each of the crosslisted courses. The total should be equivalent to the instructional offering limit displayed under the course title in the upper part of the screen.
Course Reservations  Classes
Indicate the course whose students should be placed in the given class (note: if there are more seats available in that class than how many are needed for the course, then the class is open to students from the other crosslisted courses too). See the Notes section for an example.

Notes
Course Reservations on a Class  Example
The following example provides further explanation of setting course reservations on classes:
Lecture 
2 classes of limit 40

Recitation 
4 classes of limit 20

Laboratory 
8 classes of limit 10

Individual Study 
1 class of limit 80

Lec 1
 Rec 1 reserved for course A
 Lab 1
 Lab 2
 Rec 2
 Lab 3
 Lab 4
Lec 2
 Rec 3
 Lab 5
 Lab 6
 Rec 4
 Lab 7
 Lab 8
Ind 1
A crosslisted offering consists of 2 lectures, 4 recitations, 8 labs, and an individual study.
Recitations are grouped under lectures, and labs are grouped under recitations (students from Lec
1 must be assigned to either Rec 1 or Rec 2 but not Rec 3 or Rec 4 etc.). All lectures have a limit
of 40, recitations 20, labs 10, and the offering is crosslisted between courses A and B with limits
of 20 and 60 respectively.
Setting a course reservation on a class or a set of classes for a crosslisted course means
that students from this course can only attend this class (or set of classes) among all the classes of the same scheduling subpart. For instance, if there is a course reservation for course A on Rec
1, this means that students of course A must attend Rec 1, and they cannot attend Rec 2, Rec 3 or
Rec 4.
If subparts are grouped, a course reservation automatically applies to the parent class as
well as the child classes (reservations only need to be set on one level). In the above example,
this means that students enrolling in course A must attend Lec 1 (they have no other choice since
they must attend Rec 1, however, only 20 spaces are available to them) and either Lab 1 or Lab
2. They must also attend Ind 1. The same result is achieved by setting a course reservation for
course A on Rec 1, or setting it on Lab 1 and Lab 2 (students must attend either Lab 1 or Lab 2,
therefore they have to attend Rec 1 and Lec 1 as well). Reservations could also be set on Rec 1
and Lab 1 and Lab 2 with the same effect. It also makes no difference extending the reservation
for course A to contain Lec 1 as well (students of course A cannot attend Lec 2 because they
have to attend Rec 1).
Course reservations restrict what classes students of a crosslisted course can and can not
attend; however, they do not necessarily restrict students from other courses in the crosslisted
set from taking those classes if there is additional space. This means that only the appropriate
number of seats given by the limit set on the crosslisted course is reserved. In the above
example, since the limit on course A is equal to the limit of the reserved class Rec 1, no other
students can attend Rec 1. This automatically means that students of course B are restricted to
take either Rec 2, Rec 3 or Rec 4 (and appropriate lecture Lec 1 or 2 and laboratory Lab 38).
However, if we set a course reservation for course A on Rec 2 as well (students from course A
can now attend either Rec 1 or Rec 2), up to 20 students enrolling in course A will be split
between Rec 1 and Rec 2 (using the builtin student sectioning algorithm that minimizes the
student conflicts), leaving the remaining spaces in Rec 1 and Rec 2 for students of course B.
