How do the SAT tests work?

<p>I am in my last year of the MYP, so that is year 11/grade 10. I am moving schools next year and at my new school it is required to take the SAT as well as do the IB. Can someone help explain the SAT to me. So from what I understand that there are two types of SAT tests, the normal one and the subject tests.
How many subject tests should I take?
How do the the subject test differ from the IB, in biology, math, history and chemistry?
Do you usually take the subject tests first or the other one?
What subject tests do universities generally like to see?
I'd really appreciate it if you answered just a few of these questions!</p>

<p>The SAT reasoning test is the one that is akin to the ACT. It’s composed of three sections: critical reading, writing (which includes an essay section), and math. The whole test ends up being more than three hours long (you can look up exact times online). SAT subject tests are one-hour long tests that only focus on a specific subject-math, world history, Spanish, etc. Many more prestigious schools will ask for two SAT subject test scores. The advice is to take the ones that you’ll score the highest on, but certain engineering schools will require you to submit Math II. And I’m not in an IB curriculum so I can’t answer your question. Best of luck, and contact me if you need more info!</p>
