Your Unit 4 Test is tomorrow. You got a batch of review materials today, which you can find online here. If you’re interested in reviewing the noted summary of differences between the binomial and geometric models, you can find it here.
I encourage you to work on additional problems from the textbook. I can provide answers on request.
If you have an active IXL account from another class, you could also check out the practice modules in sections X and Y of the PreCalculus section of IXL. Even if you don’t have an account, the system should let you do about 20 problems, which might still be useful!
