<p>Hi. I am going to be taking AP Chemistry next year. Several people said that they downloaded the “Chemistry Made Easy” Flash App for their TI-89. I was wondering if it is any better than this program:</p>
<p>[Alchemistry</a> - ticalc.org](<a href=“http://www.ticalc.org/archives/files/fileinfo/273/27300.html]Alchemistry”>Alchemistry - ticalc.org)</p>
<p>I have been using this program this year in Chemistry and it has done everything for me. Are there any signifiant differences between these two programs? Thanks!</p>
