How screwed am I for the SAT Chemistry test?

<p>Here’s the situation, I have to take an SAT Physics or Chemistry test for some of the technical colleges that I am applying too. The problem, though, is that I am currently taking Physics as a senior which means that I have to take the SAT Chemistry subject test. The problem is that my school only has a regular chemistry course which means that a lot of the topics on the test I’ve never even learned before.
I took a real CollegeBoard practice test and I only got a 500 because there were so many things on the test, I’ve never even seen before. I have to take the test in November because I have something planned for December. How screwed do you think I am for this test? Is there anything I can do to do somewhat well on it? What should I do?</p>

<p>According to Wikipedia, SAT chemistry scores have a mean of 648 and standard deviation 110. Right now, you have quite a bit of catch up to do.</p>

<p>Anything’s possible though. If you can pick up the topics you missed in the next few weeks, you should be fine.</p>
