I am encountering issues with the repetition of results in this code (in the terminal) I saw each result 4 times. May the problem i used the same sorted\_dic i am not sure.  
I wrote

for q in 1:4 # number of school  
standard = {Float64}()  
for i in students\_4schools  
push!(standard, S[i] \* W/ (f[i])  
end

```
     dict_standard = Dict(students_4schools[q] .=> standard)

    sorted_dict = Dict(sort(collect(dict_standard), by=x -> x[2], rev=true))

  School_one=collect(keys(sorted_dict))[1:30]
     School_two=collect(keys(sorted_dict))[1:30]
    School_three=collect(keys(sorted_dict))[1:30]
     School_four=collect(keys(sorted_dict))[1:30]

```

Please provide a working example with runnable code (just create some dummy data for `students_4schools`.

Also check that your code is working - `standard = {Float64}()` has not been valid syntax for a long time.

Also note that a `Dict` is a unordered collection, so sorting the entries does not work! If you need an `OrderedDict` you can use the implementation in [`OrderedCollections.jl`](https://juliacollections.github.io/OrderedCollections.jl/latest/ordered_containers.html#OrderedDicts-and-OrderedSets-1).

thank you for your reply.  
itried to write just allSchools=collect(keys(sorted\_dict))[1:30] then it solved .
