SAT Chemistry Questions

Some questions regarding the Chemistry subject test:

  1. Do I need to memorize the activity series?
  2. How much organic chem do I need to know?
  3. What's a good resource to study the "random knowledge" questions it tests and the laboratory questions? For example, the first practice question on the website is "carbon dioxide reacts with methane to form acid rain" or something. I struggle a bit with those kinds of "random" questions.

Thanks

Whoops, the first question is actually “the combustion of fuels containing sulfur leads to the production of acid rain”.

bump. I need help as well
