I have received OP's edu email vouch copy.

Successfully activated a new Github Education pack too.

However it seems like the edu email has a chance of getting removed anytime as I do not think it was obtained legitimately (by being an actual student).

My verdict : OP edu email works (for now), with a risk that it might no longer be usable in days/months/years. If you want to simply get an education pack quickly and change email address, I guess you could say OP's method works quickly at least for the verification for now.

Disclaimer : I claim no responsibility if OP decides to start giving fake accounts or accounts stop working.
My vouch applies solely to said vouch copy which works at time of posting.

I will update this review if email becomes obsolete, no longer works.
