If function, false, blank.... need help!!

CC rubric.xlsThere is my problem:

I have an evaluation sheet with 2 main columns (column A, column B), which I will fill with sentences from another sheet using IF function unless there’s something better.

My other sheet is working like this:

I have to attribute a score (1 to 5), and each score have a sentence attach to it… So for scores 1 and 2, I want those sentences to go in column B, AND 3, 4, 5, goes in column A.

I have 25 blocks that I have to put scores 1 to 5.

So I’m looking for:
- each sentences to go in their respective column (A or B);
- if a sentence is in column B, I want a blank in column A, BUT if I put another sentences in column A, I don’t want a big BLANK space before.
- I want the sentences in each column to follow each others like normal text.
- I have to print 2 sided sheets, so if one side is full, I want it to go on the other side.

It’s a lot to ask, but I need an expert, because I’m stuck!!

Thank you
