I took the old one, so I doubt I'd be much help to you, but TC's advice is solid. Set a steady pace, stick with your answers, and it's just like any other standardized test. Personally I loved the SAT, took it 3 times and probably only got into college because of my score (I had given up on school and stopped caring around 7th grade).

Like most tests the SAT primarily measures your ability to take tests. If you're a good test taker you only need the minimum of actual knowledge to cruise through.
