Hey there, fellow brainiacs! Let's talk about something super important for AP exam day - calculators. Yep, those little gadgets can make a big difference, but there are rules you gotta know.

So, here's the deal:

First off, not all calculators are allowed. There's a list of approved ones, and your proctor will be checking them before the exam starts. You can bring up to two permitted calculators, but make sure they're ones you know how to use and they're in good shape.

Now, here's what you can't do with your calculator:

• Sharing: Nope, you can't pass your calculator to your buddy.
• Communication: Your calculator can't send secret messages to other calculators. It's strictly for math!
• Memory Tricks: Don't even think about using your calculator's memory to sneak out test materials. If you try, your scores will be canceled faster than you can say "equation".

If you're not into using a calculator, that's cool too. But, if you decide to go calculator-free, you gotta sign a form on exam day saying so.

Now, let's break it down by course:

• Biology: You can use a scientific or graphing calculator for both multiple choice and free response.
• Calculus AB & BC: Graphing calculators are a must for both parts.
• Chemistry: A scientific or graphing calculator is recommended, but a four-function one will do.
• Environmental Science: Scientific, graphing, or even a simple four-function calculator is allowed.
• Macroeconomics & Microeconomics: Stick to a basic four-function calculator.
• Physics 1 & 2, Physics C: Anything from a scientific to a graphing calculator is fair game.
• Precalculus: Details will be in the calculator policy for the 2023-24 exam.
• Statistics: Graphing calculators are the way to go.

But remember, no calculators for Computer Science exams unless you've got special permission.

Alright, now for the big list of approved calculators:

Casio

Hewlett-Packard

Radio Shack

Sharp

Texas Instruments

Other

And of course, there are things you definitely can't bring:

• Phones, smartwatches, or any wearable tech
• Tablets, laptops, or any portable computers
• Models with QWERTY keyboards or pen input
• Anything that can access the internet or make noise

Phew! That's a lot to remember, but don't stress. Just double-check everything before exam day and you'll be all set to conquer those numbers!
