I am trying to make a quizzing system which makes a troublesome area of questions appear more or less depending upon the amount of times they succeed or fail at that question within a record. Each record has a question.

 

I understand how to go to a random record by calculation 

But I am looking to (by calculation) change the possibility of a record being viewed.

I tried adding or subtracting duplicates of a given record

but then I have the problem of removing an original record which I don't want to do.

 

My difficulty and need here is to find out how to simply increase the possibility of a record being viewed more often by script or as it is mastered (the answer) a scrip that will lesson the amount of times that question is viewed. 

 

If there are 10 questions (records) at the outset, that means based on the total record count each record accounts for 10 percent of the total . With 100 questions each record becomes 1 percent of the total etc. 

 

I would like to add two buttons that change the percentage of time that record might appear randomly (either more or less frequently) an add button to increase the frequency slightly that the random record (with problems answering ) shows up. and another button called lessen where it lessons the frequency of that record showing up randomly because that question has been mastered in that record. 

 

I have attached an example of what I am trying to do.

In my example it simply adds a duplicate of the problematic question if the user selects that button

or it removes the record if it is mastered. 

This all words find but I don't know of a way to at least keep one copy of the record. I don't want to loose the record entirely even if it is mastered.

This seems like a duplicate of your earlier post, here.

See if this helps:

Why not a simple Omit Record ?

Is it possible with the same file to somehow do a portal to keep all the questions intact? If that is the case I am not sure how to change the random formula to make the hard to answer questions come up more often.

With my example all the questions remain intact.

To make the hard to answer questions come up more often you can use your "add" button.
