I will have any problem if I entered my personal e-mail instead of my school e-mail to create my account for the student version?

Hi @Maria Tiniganay​ 

I have a feeling the application won't be accepted with a personal email. See the FAQ on this

If you email CustomerService@SheerID.com  they should be able to advise whether they can change your email or they might just ask you to reapply with the correct email
