Configuring my practice exams - please help

Good day everyone,

I'm trying to get some different configuration in my exams, what im trying to do is this:

Each practice exam I have consists of 60 multiple choice questions.  What I would like to do is to have the first 15 questions available for FREE to all students.  However, after students view the first 15 questions, they would need to purchase the full-length exam to get the rest.  So...I would like to have two buttons for each practice exam (somewhere on the website) that says "Free Trial" (which would unlock the 15 free questions) and "Purchase Full-Length Version."  

Do you guys think this is this something that can be done normally in moodle? or what should i do?

Thanks in advance for everything.
