[Using Sakai] Timed Courses

[Justin Swanson]

Need to time a course. Meaning, you need to read and review the course  
for a total of 100 minutes before you can move on to take that  
particular courses test and then also move on to the next course.

For example:
- Course 1 is 100 minutes. After the 100 minutes is up, course 1's  
test is "unlocked" for you to take (you can take as long as you need  
for the test - no time limit). You have 2 tries to pass the test. If  
not, then you must call us to retake test.

- After you pass course 1's test, then course 2 is "unlocked". You  
have to take course 2 for 100 minutes before you can can course 2's  
test. After you pass course 2's test, you can move on to course 3.  
etc. etc. etc.

Does Sakai offer this option or maybe as a module or plugin option?
