<p>So what programs are a must have on this calculator for these tests.</p>
<p>None…I scored 800’s without using any calculator programs.</p>
<p>However, some built-in calculator functions are worth knowing. For example, if you want to define a function f(x,y) = 2^x + 3y, input it as usual, but put a colon after f(x,y). nsolve can help for certain functions that can’t easily be solved otherwise (x + sin x = 1).</p>
<p>Keep in mind that all PSAT/SAT questions can be solved without use of a calculator.</p>
<p>None. It will take you longer to find and use these programs than it will to learn basic techniques an just observe the problem. it will be faster and easier just to learn the stuff, as well as a better use of time than running around looking fro cool programs.</p>
<p>Okay thanks!</p>
