<p>1) Do I have to know how to calculate buffers?</p>
<p>2) How important is hybridization? I have surface knowledge, should I study in-depth?</p>
<p>3) How much do you suggest I study for laboratory set-up/qualitative tests/laboratory equipment?</p>
<ol>
<li>Good to know it, but since buffer takes time, its good enough to just know acid base neutralization.</li>
<li>No; surface knowledge is fine; there is one or two questions are most asking you about the hybridization of a molecule.</li>
<li>If you have the Barron's book; you are good to go if you know all their ridiculous lab setups. Know the color tests, they show up a lot. Know some general colors of compounds. Know some general processes of making common compounds such as distilled water and nh3.</li>
