We need the ability to add prerequisites that would allow multiple paths to the same course. For example: You want to take US History I - H you can have either an 86 in World History H or a 90 in World History. We have several courses like this and like the example given by the Ana where you may need to take more than one course at a certain level. It would be nice to be able to have the computer do this rather than have each of my teachers do recommendation.

We too need the option to be able to enter prerequisites with an EITHER / OR with an AND as well.  So in order to take a course, the student must have (EITHER x course OR y course) AND also z course.  Additionally, it would be nice to have a concurrent enrollment feature (the system checks to see if the student selected the concurrent required course). When it comes to Math and Science prerequisites, I agree that we need more options.

I concur.  I am trying to set up prerequisites for the first time and the conditional logic we need to to capture the true requirements is not available with the current options.  To allow a blend of "One of the following" with "All of the following" would be better.  Best is to allow "One of the following" AND another "One of the following" to capture the math and science requirements for certain science courses. 

This is an important feature we need.   The current options do not support the spread of prerequisites that we need.  We have some absolute prerecs, but we also have some recs that can be met by one of several options.
