Dear Ms. Arusha,
Is it me who addressed your reply? Anyways, I have gone through your presentation and I need time to suggest necessary modifications. Kindly email me a copy to my email ID. Kindly make a note of certain points while designing presentations:
1) The objective of the presentation should be clear.
2) Emphasize (deep focus) on the benefits (to the school and students) of the objectives of the presentation/topic/agenda.
3) Correlate with a few examples for easy understanding.
Understand your school authorities' requirements before you deliver the presentation because it is very difficult to read human minds through their faces.
For further queries, please feel free to write to me.
With profound regards,
