<p>I need a new calculator...as the other one has mysteriously broken.</p>
<p>Point being, I will be taking AP Calc BC this year. I, also, plan to use it on the SAT ML2 and in physics.</p>
<p>I noticed the difference in price between the 89 Regular and Titanium. Which do you suggest I get? Is there a big difference between them in regards to their functions?</p>
<p>It seems like Titanium just has more memory and is faster. Is the regular 89 slow compared to, let's say, 84 Plus? I don't know if I will need more memory, but I doubt I would...</p>
<p>I use mine all the time in calc class and used it in ap chem a bunch last year. as long as you okay it with your teachers, you should be fine (it can do some amazing stuff). Like i wasn't allowed to use it on one quiz last year in p-calc, but other than that i was good.</p>
