Is 'Raise your hand' correct? Is Extreme end tautology?

If your teacher had taught you that  'raise your hand' is wrong,  just know that you have been wrongly schooled.
You can say 'raise your hand'  or 'put up your hand'.  Meanwhile,  'raise your hand' is more frequently used.
'raise up your hand' is tautology .

"Have you seen a movie? "

The 'see' here implies having sat in a Theatre/cinema to watch a movie.  It is still correct to say one watched a video.  I mean,  who were these people who began teaching these wrong English expressions. 

Bogus doesn't mean 'oversized' rather it simply means 'untrue'

By the way...  'Extreme end' and 'extreme limit' are correct expressions. They are boldly written in the dictionary.  Ask Professor Joy Eyisi,  she will tell you that these expressions are  proper English expressions.

Those of you that are keen on correcting me, please do.  I am here to learn as well.  That's why I have you here.

I love you all
