5th and 4th week, warm up and so singles until you reach a weight that you can do a triple with, and do 2 sets of triples.
3rd and 2nd week, do the same as above but with doubles.
1 week away from meet, work up to a 1RM and get a feel for your opener which should be an easy one that you know you can do without much effort.
Don't do anything until the meet, no working out at all.
On meet day, make sure you eat and are well hydrated. Open as above, 2nd attempt go for a 5 lbs PR, on your 3rd go for broke.
Have fun and learn.
