Enter value for 6 rows then skip 6 rows and go all the way to end

I am trying to tag the first 6 rows out of 12 and then do it again for the next block of 12 rows (each Week has 12 rows).  this is to tag who is the top 6 scores out of 12 people each week and there are 13 weeks of data.  So I want to create a column that puts 1 for the first 6 rows out of each 12 and keep doing that wherever there is score data.  

I would another field that is exactly the opposite - tag the last 6 rows out of every 12 with a 1 (if there is score data).  Is there an easy way to do this with the Multi row formula?
