As you know, BCSM is NOT providing you with calculators this year.
If you don’t have access to a graphing calculator, the first thing you need to do is download Desmos to your phone or tablet for use at home. Desmos is an online graphing calculator. Obviously, you can’t use Desmos on any class exam or the Regents, but it is a GREAT tool to use for your homework and studying.
They’re not cheap, but sometimes you can find deals on sites like eBay and Amazon. Staples occasionally runs sales. If anything comes my way, I will pass it along.
