Hjælp til forståelse

Hej,

Jeg har fundet frem til denne kode vha mange google søgninger og den virker på mit system, men mit problem er, at jeg ikke rigtig ved, hvad det er jeg gør. Er der nogen, der kan hjælpe?

    lrow = tmpsh.Cells(Rows.Count, 1).End(xlUp).row
    dRow = 2
    tmpsh.Cells(2, 3).Formula = "=CountIf(Base!A:A,A2)"
    tmpsh.Cells(2, 3).Copy Destination:=tmpsh.Range("C3:C" & lrow)
    i = 2
    While tmpsh.Cells(i, 1) <> ""
        If (tmpsh.Cells(i, 3) > 7 And tmpsh.Cells(i, 2) = "Master") Or (tmpsh.Cells(i, 3) > 1 And tmpsh.Cells(i, 2) = "Bachelor") Then
            dsh.Cells(dRow, 1) = tmpsh.Cells(i, 1)
            dRow = dRow + 1
        End If
        i = i + 1
    Wend
    tmpsh.Delete
    dsh.Activate
    For i = 2 To dRow - 1
        dsh.Cells(i, 2).FormulaArray = "=OFFSET(Base!A1,SMALL(IF((Base!A:A)=A" & i & "*(Base!M:M=MAXIFS(Base!M:M,Base!A:A,A" & i & ")),ROW(Base!M:M),""""),1)-1,1,1,1)"
        dsh.Cells(i, 3).FormulaArray = "=OFFSET(Base!A1,SMALL(IF((Base!A:A)=A" & i & "*(Base!M:M=MAXIFS(Base!M:M,Base!A:A,A" & i & ")),ROW(Base!M:M),""""),1)-1,3,1,1)"

        DoEvents
        dsh.Cells(i, 4).Value = GetSemesterFromErollPeriod(dsh.Cells(i, 4).Value)
    Next i
    dsh.Columns("A:G").AutoFit
    dsh.Range("A1:G" & dRow).Copy
    dsh.Range("A1:G" & dRow).PasteSpecial xlValues
