How to work fast for time-limited chem quiz?

I needed some suggestions for taking a chem quiz (written) tomorrow. Basically its a 4 part chem quiz that we are supposed to do in 30 minutes, and it' sout of 20 points but there are an additional 15 points for bonus on this quiz. Now he made the quiz so that 30 minutes will be very tight for getting through the whole quiz on time, and I wanted to get as many bonus points as possible. Thus, my question is, what can you guys recommend to work fast/efficiently/correctly because i am a very slow/analytical thinker and I prefer to do things slowly.

Peace.

Sorry Hermit, I don't really think there are tricks to working fast on O-chem. The better you know the reactions, and the more practice you have, the faster you will go. I would do practice tests under timed conditions so that you know how to pace yourself. Pacing is one thing that you can do to help your score- ie, keep the clock in mind, and don't spend too much time on any one problem. If you get stuck, scribble down what you can, hope for partial credit, and move on.

Good luck

1. I use this pencil with an auxilliary eraser:

2. For large molecules with mechanisms... define the part not involved in the reaction as "R1" "R2" etc to avoid having to write out the whole thing again and again during the mechanism

For instance. blah..blah.. C=O

Define blah..blah as R1

3. Write out primary formally, solve algebraically to get final formula, then plug in numbers. If you make a mistake, you can easily change your answer because you already have the rearrangement in algebraic form.

4.Use a TI-89

5. Know the problem types

6. And lastly do everything you can possibly think of, but sometimes the answer to a seemingly complex puzzle is right in front of you.

For instance, sometimes things are simple... like if the prof puts a Grignard reagent in with a proton source that is acidic enough.. then you are just going to get an acid-base rxn instead of a nucleophilic attack. Remember N.R. = No reaction

wait - are we talking about a GENCHEM quiz, or an OCHEM quiz? And.. what topics are going to be on the quiz?
