I need help with Google Chrome?

[Sofia]

So I have google chrome on my home computer and my school computer. I was signed in to my at home gmail account on my school computer so I could have the theme, but all my bookmarks that I have for home are on my school computer, and I know I could get in trouble. So how do I sign out? I heard you can't sign out, but I really don't want to delete my account, I use it often.
Btw, I have bookmarks like Facebook, Tumblr, Minecraft, etc. just so you don't get any funny ideas on why I may get in trouble, haha.

go to the right bottom corner of Google Chrome and click on Web Store to open the Chrome webstore.

At the right-top of the google chrome webstore page, you will see your gmail account name.

Click on the down button next to your gmail account name and choose logout.

OR

go to Google Chrome settings

click on 'unlink your google account'.
