I am freaking out about my Sat, Iowa, and ISEE tests. The test is in three weeks and my parents won't get me a tutor and I think I'm going to fail. Is there any advice you can give me about taking them?

Take a graphing calculator or a standard one. It will make the math section easier. Practice on reading faster and comprehension skills. My son took his act in the spring and is going to take it again. This was his advice. Good Luck

There are books at the library that can help study for the SAT. There is an online help, that states it is free - SAT Practice Questions - Help your SAT Test Score with free SAT Test Preparation Materials (http://www.testprepreview.com/sat_practice.htm)
Like Bushg said, you can take the test again. Sometimes the second time around works better - you don't have that first time anxiety.

Those are all quite different tests.

The SSAT doesn't allow calculators. The Iowa tests are designed to measure progress in school overall, and are easier than the SSAT. The SAT is a test intended for high school students applying to college.

So, how did it all turn out?
