I can make a powerpoint presentation for you!
I hope you realize offering any sort of academic “help” or to do school projects will get your Gig denied and taken down. May not be today, or tomorrow, but they will find your Gig and erase it. It is against the TOS to offer any sort of “help” with school projects.
Also, this does not belong under the “Your Fiverr Experience” category - if you want to hawk your Gigs to the masses, you need to place your post under the “My Fiverr Gigs” category.
