Hi,

You could use a formula to compare the 2 lists

=IF(ISERROR(MATCH(C3,$A$1:$A$3,0)),C3,"")

This macro will extract the unique values from list a (assuming range A2:A last used row) and list b (assuming range B2:B last used row) and put it in Column c.

Option Explicit

Sub Demo()

    Dim c As Range, d As Range, LR As Long
    Dim i As Integer

    For Each c In Range("A2:A" & Range("A" & Rows.Count).End(xlUp).Row)
        If Not WorksheetFunction.CountIf(Range("B2:B" & Range("B" & Rows.Count).End(xlUp).Row), c.Value) >= 1 Then
            i = i + 1
            Range("C" & i).Value = c.Value
        End If
    Next c

End Sub

Enter it in the Microsoft Visual Basic Editor, then run it from the macro dialog.

To open the VBE (Visual Basic Editor), in 2007-2013 make sure the developer tab is visible.
If the tab does not show up on your screen, you can add it as follows:

For Excel 2010: click the File Tab then select options. On the left hand side of the Excel options dialog box, click Customize Ribbon. Then, on the right hand side box select Developer.
2010
For Excel 2007: click the Microsoft Office button, then Excel Options. In the Popular category, under Top Options for Working with Excel, select Show Developer Tab in Ribbon.
2007
Click the Developer tab on the Ribbon at the top of the screen.
Click on the Visual Basic icon in the Code section.
Click Insert from the VBE menu.
Click Module
Copy and paste the macro in the module.
Run the macro from the macro dialog http://www.dummies.com/how-to/content/how-to-run-an-excel-2010-macro.html

Uncanny similarity, as if you both have the same homework being set???
