Khan Academy directions for Extra Credit on Test 7.3

Khan Academy directions for Extra Credit on Test 7.3
For extra credit you can do the following exercises on Khan Academy. Your goal is to get 5 in a row for each section. Even if you don't get 5 in row, keep trying and I'll give you some credit. I'll be able to see which ones you got right and wrong, how many minutes you spent in each questions and which videos you watched. It's really cool. Here are the directions.

1-      Join the Khan Academy (KA) it's free.
a.       Go to https://www.khanacademy.org
b.      Log in using Facebook or Google
c.       Take the pre-test that will pop up automatically
                                                               i.      Just 10 questions, don't worry if you miss… just knock it out…
2-      Next you should join my class "Alg 2 Batista"
a.       From your "dashboard" look at the left column and click on "Coaches" which should be the last option on the left column
b.      Add me as your coach by  putting the , code S3V5YQ  to join my "Alg 2 Batista" class.
c.        
3-      After you've logged in and joined my class, do these exercises to get the extra points. Just click on each link… You should try to get 5 correct in a row, or do 10 questions total (in each section). The more correct the more points you get.
