<p>I am giving the SAT subject test for chemistry and bio tomorrow. I have prepared pretty well for bio ,but not for chem. All i know is what ive learned in my chemistry classes from grades 11 and 12. I was wondering, to calculate pH how are you supposed to do the log calculation WITHOUT A CALCULATOR or LOG TABLE? Also, anyone have any tips for the exam? I need help with organic chemistry</p>
<p>There’s usually only 1 of the 90 questions on organic, so don’t worry.</p>
<p>I will help of you give me specific questions.</p>
<p>Thanks college life 543.
