<p>1) Get out your TI-83.
2) Go to Google. Find a list of prime numbers.
3) Start a new program on your TI wherein you simply LIST all the primes up to 100 or 150 or so. Separate them by commas. Just make that list the first line of the program and then close the program.
4) When the SAT asks you a question about primes, simply go to Edit under the programs menu, choose your program (I called mine PRIMES) and you'll have the list all ready to use.</p>
<p>Notas Bene: </p>
<p>--Make sure your list is accurate. Double-check it with a second website. Then: TRUST IT!
--Make sure you get good/fast at accessing it so you can do it quickly in the heat of the moment on the SAT and it won't cost you time.
--The collegeboard website says explicitly that you do NOT have to delete programs from your calculator, therefore this awesome trick is 100% allowed.</p>
<p>There are always AT LEAST a handful of prime number problems on the SAT. Save yourself some time. I was stupid, I didn't use a program like this. I missed 2 problems about primes and got a 780 (from careless errors with prime numbers, not to mention a bunch of wasted time listing primes!). </p>

<p>Where does it say this? I'd would LOVE to know. At the last SAT (Jan.22), I had programs on my calculator, and the prompter said she was going to walk around to check our calculators for programs. Well, I got so scared that I put my calc in the pocket of my hoodie and took the dam test without a calc. I was scared that you weren't allowed to have programs on your calc. So I am pleading for a URL so that I can rest assured my loaded TI-83 will be of use to my this Saturday. Thank you.</p>
<p>The TI-89 has programs pre-loaded and they don't make you delete those. So I don't see how they would know about this. I took the SAT 3 times before I reached high school for a talent search thing, and not one proctor checked my calculator for programs or anything. And I took the SAT with other high schoolers at the time too, and no one was checked. </p>
<p>they didn't check my calculator when I took it in December...but uhh...prime numbers will be the least of my worries lol...give me the answers and I'll be set :)</p>
<p>Isn't this kind of cheating? Besides, it's not that difficult to just remember the prime numbers, unless you have some kind of mental block around them.</p>
