# IB S1 FINAL REVIEW KEY (UPDATED!)

Yes. You are privileged to have a teacher who gives you a key for the final review so dog-on early!

Here it is. I’m giving you a clean pdf of the review without markups for those who like to go over it more than once. I changed a few things:

#1, 4b, 9, 10d-f, 11, 12 are different. I added Logic to the end as well. (SEE THE BOTTOM FOR THE CHANGES!)

And so the key represents the final I gave out, not the one above.
