Mechanical properties and extrusion tests not yet performed
Mechanical properties and extrusion tests have not yet been performed
or
Mechanical properties and extrusion tests have not been performed yet
Which sentence is correct?
Thanks in advance
Marco
They are both OK, but the first sounds much better, as the sentence is somewhat formal and it makes it clearer that they will be performed, but it has yet to happen.
