The pre-requisite for Shormann Calculus is the successful completion of Precalculus. If you believe your student can skip Precalculus, take this placement test under parent supervision with a one-hour time limit and no notes or other resources: Saxon Calculus Placement Test
If your student passes the placement test, they should be ready for Shormann Calculus. However, once you access the Calculus eLearning course, there are no refunds or exchanges. So, if the student struggles and decides to go back to Precalculus, we can put Calculus on hold. But, we cannot exchange it for Precalculus. You will need to purchase it at regular price.
