Are you wanting to complete Math 10C, but are not confident in your math skills?
Do you need to work on your math skills to prepare you for Math 10C, while at the same time earning 5 credits for Math 10-3?
Take Math 10 Prep in the summer.
Or.... take Math 10 Extended - Offered at SACHS in the fall -
Another alternative is to register for Math 10 Extended at SACHS in the fall. It is actually two courses combined into one full year course. The first 3-4 months is spent preparing for Math 10C during which time you will also get credit in Math 10-3. Then in December you start working on Math 10C. This gives you 7 months to finish, instead of 5.
