Yo If You Want Your Chromebook Unblocked Then
1. Type In Chrome://SignOut And Log Out Of Your School Account
2. Type In Chrome://Restart
3. Type In Tinyurl.com/addsession And Log Back Into Your School Account
What This Does Is It Removes Your Cookies Your Administrator Added On Your Chromebook
You Can Use The Same Trick When Your Administrator Blocked Your Website You Go To
BTW Im Not Responsible If You Get Suspended Or Any Kind Of Trouble By Using This Trick,
Also, My Administrator Uses Securly To Block My Websites So It Might Not Work On Other Stuff Like Go Guardian
