Hi Everyone,

I would need your help to review my powerpoint presentation. Any suggestion will be much appreciated.
Any use of tools (AI,software) to improve the slides and content would be much good as well.

I am looking at what marginally I can do at the moment rather than doing an overhaul (e.g font on which page, etc)
