Take it multiple times unless you get an absolutely outstanding score on your first try. I did it 3 times and got a 32. I was very happy with that.
Some tips. There will be a lot of questions that you have no fcking clue how to solve. This is normal and expected.
Study calculus as much as you can. Derivatives, integrals, related rates, the whole lot. Over preparing is the best strategy, but ask your math teacher specifically what they'll be asking, concept wise.
Science is another big one. You'll need decent amounts of chemistry knowledge and also just general scientific critical thinking skills.
When you get to the reading part, they purposely do not give you enough time to read the stories. Learn how to skim through them and get only the parts you need.

Calculus isn't at all necessary, but it could be helpful. The science portion is mainly about reading the questions, tables, and data that they give you. Almost every answer is given plainly on the page. As for the Reading section, you should get used to skimming, yes, but the strategy is to skim so that you generally know where the information you need is for each question. Unless you have trouble reading quickly, don't be too scared to take your time to finish the article.
