Module development and code questions

Hello!
I have never seen this online before (my request)...

I would like to be able to restrict areas on the website. Members may try to gain access by taking a quiz. The quiz can/could be configured to show questions one at a time. The users results determine if they can be allowed to enter (upgrades permissions?) If they fail then they cannot retake the quiz (if setting is set).

So each time a user passes a series of questions their level can increase or get points.

Each quiz can contain unlimited questions/answers.

So to recap.

After I installed the Subscriptions module, every post should have a "subscribe post" link. But this is not happening on my site. Some posts just don't have that link. I cannot figure out the reason.

Can i make a block with choice menu ? I want the value of menu choice will affect some page,so how can i do that ?
