Delte a specific column and does not delete the top row

Hello,

I would like ask help from you guys. I have encountered a problem that I cannot delete a specific column only and also does not delete the top most row of the active sheet. I wanted to delete all data in columns A:C and K:W but I have tried so many codes I cannot pursue it. Please help. Here's the code. All characters in Bold format the problem that I encounter.



Sub Start()
'
' Start Macro
'

'
Sheets("SEGREGATION").Select
Cells.Select
Selection.ClearContents
Sheets("UNCLASSIFIED").Select
Cells.Select
Range("A13").Activate
Selection.ClearContents

Sheets("CLASSIFIED").Activate
Columns("A:C").Activate
Columns("K:W").Activate
ActiveSheets.UsedRange.Offset(1, 0).ClearContents
Sheets("INSTRUCTIONS").Select

Thank you in advance.
