hi joseph!
You'll do fine :-)
In your presentation, have the usual title, introduction, rational, objectives etc.etc.
Speak about your project, and what you have done so far.
If you have results, present them as well!!
You don't have to spend too much time explaining the results, but say something :-)
It is also helpful to have your next "phase" ready (at some point in the presentation), or you dont have to put it in the presentation, but you can speak briefly about it... "from this...the next step will be to do...."
I think your supervisor will be with you during this progress presentation?
You'll be ok. good luck
