How can I hack my teacher's account and change my grades?

I am failing a class and want to change my grades. How do I do this? Here is a list of everything I have tried so far:

  1. Asking kindly for her password

  2. Doing a heartbleed attack on the mouse drivers of her account

  3. Bruteforcing the UDP drivers of her account

  4. Cracking the ARP hash that I got by doing a pixie dust attack on her account

  5. Uploading a backdoor (it was generated with nano and then encrypted to base64 using Nmap) to Active Directory using LOIC

  6. Called her office claiming to be the custodian saying I need her password in order to sweep the main lobby

  7. Used mdk4 to test if her account is vulnerable to any exploits on exploit-db

  8. Did a pass-the-hash using the ICMP-encoded version of her email address (I used md5sum to perform the attack)

  9. Hacking her computer using GeekTyper

  10. Ran "color a & tree C:\" on my computer

Not sure if it helps, but number 10 just showed me "aHVudGVyMg==" as the password, but that didn't work, so I am guessing that is an AES-256 version of her password.

Now I am lost. Any other ideas? I really need your help.
