Setting Variables for a Calculation

[etsmarines]

I am trying to set a calculation to a field to auto update a "class of" year based on a students current grade. My calculation will look at the students current grade and set a variable value based on that current year value. Then it will add the variable to the current year and return a year in a "class of" field. My calculation that im trying to do looks like the following below but it will not let me do it because I get an error that says list usage is not allowed in this calculation. Please help me I dont know what I'm doing wrong.

Let([PK=13;K=12;1=11];child_1_grade+Year ( currentyear ))

Thanks For The Help!

And I don't know what you are doing... Why are you declaring variables that you don't use? And of course, you cannot make 1 equal 11.

BTW, this seems to be a follow up of:
