why I want to use WIX instead of Powerpoint....

The reason I should be able to use Wix because I really think I can improve my assignment if I have this facility and usage. Due to it being easier and more convenient  I really think that wix should be appropriate to use for our IST assignment, If we had to upload videos or images, Wix is much more easier to use and operate.

We could create an online name and use that account, privacy can be done by using options like URL LINK needed. Making the show private and not on the internet.
This is how to password protect your page:

As you can see there are many advantages of using wix rather than powerpoint, the layout and animations are used easily in WIX. And as you can see above, there are many ways of making a password protected page for wix, therefore it is very private and safe.
