How can I make multiple quizzes within one Captivate project?

Question

Hi guys! Really liking Captivate 5.5, especially the way random question slides can lift questions out of a question pool...very elegant!
Sadly though, I've come up against a bit of a wall. In my project, I want to have 3 separate quizzes that all use the same question pool; a 10, 30 and 50 question-long quiz. Each one needs to have its own results page.
It's easy enough to see what I mean by looking at the screenshot below:
The idea was to have about 105 slides in total, with slides 10 - 20 being the 10 quiz slide, 21 - 51 being the 30 question quiz and 52 - 102 being the 50 question quiz.
There are three invisible buttons placed over those 10, 30, 50 text boxes. In the picture, the '10 question' button would jump to slide 10, the '30 question' button would jump to slide 21, and the '50 question' button would jump to slide 52, jumping the user to the start of their designated tests.
Though I can create the 10 random question "block" easy enough, when it comes to adding the 30 question "block" it just adds the new random questions to the existing random questions. I want three separate quizzes, each with their own results screens please. (I don't want to daisy-chain to external projects, because the results of each test need to be used within the homepage.)
It just adds them on to the existing block!! Argh!!
Little bit ticked off with Adobe...the reason their products are so incredible is because they put no constraints on the user, and you can use their tools to create things even the developers never dreamed of. Like in Photoshop for example, I bet when the dropshadow fx was created, the developers never realised that it would be used to give a metallic 'stamped' look to text by turning it to white and applying it just inside the text.
Captivate, though amazing most of the time, has a nasty habit of stomping on my toes. You can't set grade boundaries and have quizzes give out grades A+ to F- for example. You can only have 'pass' and 'fail', thus making it rather pointless for use in schools, contrary to how the program is advertised. Another example would be when I wanted to create a replay button. I thought that a button that jumped to the slide it was on would be a simple, no-BS replay button, but for some reason you can't make a button jump to its current slide. I downloaded a widget that worked in the end, but I wish Adobe would get off my back and let me do what I want!
Anyway, if you could help me out here it would be grand

I must say I have a little sympathy for the Captivate developers on this occasion.  As you say, they've created an application that does so much, that when you eventually run into a hard boundary of some kind, the effect is somewhat jarring.  However, every application, no matter how good, has limits.  I'm probably one of the worst offenders when it comes to asking the Adobe Captivate Development Team for enhancements (I think I've logged over 70 enhancement requests for Captivate 6 alone).
In your case, you want to have three different quizzes in one project file, each with it's own separate Quiz Results page.  Lilybiri's blog explains how to set up your own faux Quiz Results pages using system variables and custom user variables, but you're going to find this to be quite a lot of trouble.  Even if YOU want to consider these as three separate quizzes, as far as Captivate is concerned they're just one big quiz with 50 questions.  So Captivate will calculate it's internal results based on a 50 question quiz, even if your users select the 10 question version.  So achieving a final Pass/Fail result is going to be problematic at best.
As Lilybiri suggested, your better strategy would be to break this up into separate modules so that you can get your three separate quiz results (all done in standard Captivate) as well as correct results based on the actual number of questions done by the user.
As far as grades A-F is concerned, there's nothing to stop you from using Advanced Actions and User Variables to calculate the user's score as a grade.  You need a user variable that stores the user's grade (e.g. var_Grade). And you need a fairly complex Conditional Advanced Action (e.g. caa_CalculateGrade) with several clauses each of which goes something like:
If
cpQuizInfoPointsscored is lesser or equal to [highest score for a particular grade]
AND
greater or equal to [lowest score for a particular grade]
Actions
Assign var_Grade with [the appropriate grade for that range of scores]
Your conditional action will need one of these clauses for each separate grade.  Once your variable has been assigned a grade based on the user's score, you can display it in a text caption somewhere on the quiz results page or on a slide thereafter with suitable commendations/ commiserations.
