Not all the time. All my 20 series classes allowed scientific calculators. Depends on the professor. Its true that it doesnt matter for physics classes. I only took one chem class and it only allowed scientific.</p>
<p>Just buy one. It’s only ~10 dollars and its good to get use to your calculator before the exams. I suggest using the same calculator for the exam as you would with homework.</p>
