VBA - Call Macros With Varying Names And On Varying Modules

I want to call a macro with a varying name that is within a module with the same name.

I have a module called Test1 and within this, a macro name called test1
I have a module called Test2 and within this, a macro name called test2
etc

On another module called Test8 (with the macro called Test8), this Test8 macro will call either Test1 or Test2 or Test3 etc depending on what I choose in an excel spreadsheet. So on sheet1, cell A1, there is a drop down with the options Test1 or Test2 or Test3 etc.

The following works to run the macro test1 from module test1 (when it does not vary i.e. i physically put in the name of the macro myself):

Sub Test3()
Test1.Test1
End Sub

The following works to run the macro test2 from module test2 (when it does not vary i.e. i physically put in the name of the macro myself):

Sub Test3()
Test2.Test2
End Sub
etc

However, if I try it so that the calling of the macro varies as below , it does not work:

Sub Test3()
MacroToCall = Sheets("Sheet1").Range("A1").Value
MacroToCall.MacroToCall
End Sub
