but all I have is this 

 I'm just curious if I have to download this brush and if so where can I download it, 

any help or advice would be greatly appreciated

What operating system are you using?

Do you have a drawing tablet like a Wacom or similar?

I believe Arrondi net pression opacité is Hard Round Pressure Opacity

Hi Jeff, 

I have a windows operating system 

and I have a Bosto 12hd drawing tablet it's like a Wacom tablet

Hi Ann.  I was going to tell you that Photoshop does not know that you have a tablet until the first time you move the pen/stylus on the tablet, and that the Hard Round Pressure Opacity preset would not display properly, as below.

Fortunately, I tested it as it made no difference for me.  I was unable to make that preset display properly.

Where this does work is in the Brush Settings panel.  The stroke preview will show as solid until you first use the tablet. After that the stroke preview will fade end to end as below.

If you don't have a tablet and your tutor requires you do make brush strokes with varying opacity, you can do this by stroking a work path. 

Make a path and have the brush selected and sized.

Right click the path and chose Stroke Path

Make sure that the Brush is selected in the drop down list, and that Simulate Pressure is checked

Which gives you this result.
