Admin Review Student visa (How to draft)

Hello friends i have question related to Admin review draft.

I want to know how i can write reply of admin review?

I have to fill admin review request application by hand and write my point of view in form by hand or i should edit pdf?

If my reply draft is long then can i type my reply separately on Word file and leave Part 2 area of the admin review request empty and then attach that Word file along with Admin review form and send email?

Kindly guide me.

You should download a pdf editor and fill that form and print it out, Sign it, scan it and send.
