Read Theory Progress

I have compared the grade levels l have made throughout the year.
On July for my grade level l got 2 because l just started using the reading program.
On November the grade level that l got was 4 l think l was getting better on this reading
program and l was getting good grades. On February my grade level was 5 l went a
level up from the last month which was November l think l did a great job because
l went up a level.  I think l did a great job because l went from 2, 4 and 5.
