MIT BrainTrust Choose Lesson BACK NEXT
Progress 3 / 8

Great!

What you see at the top of every page is called the "MENU BAR." MENU BAR contains several useful tools and information. Let's see what each part of the MENU BAR is used for.

You have already used the NEXT arrow a few times. The BACK arrow does the opposite of NEXT arrow. It goes back to the previous page.

Try clicking on the BACK arrow (Be sure to come back here by clicking on NEXT afterwards).

Try It!
