Official Full SAT Practice Test Reviews
The free practice test provided by the College Board itself is advantageous for two reasons: one, practice is practice, and having the opportunity to sit for a real, full-length SAT test is invaluable, and can only help you; even if you don't score as well as you might have hoped, you're still learning valuable time management and test taking skills. And two, it's free, which is always a plus. However, while this is a great resource to add along with other study tools, it is a poor stand-alone option; if you had to only use one study source, go with a comprehensive and, most importantly, educating text book, like the Kaplan I reviewed above.
If you are looking for a free practice test to practice the writing section of the SAT this would be my first suggestion. This official SAT practice test will allow you to write a practice essay, submit it, and receive a real score. This is something many other practice tests (especially books and print material) cannot do. The test also has questions for all the other sections and instead of scoring the test yourself with an answer key you will receive a real SAT score for your practice test.
A disadvantage to this program is that there is only one practice test to take. I would suggest taking this test about halfway between when you first start studying for the SAT to your actual test date to see how well your study plan is working and what sections you need to start focusing on.
Practice tests are available everywhere: online, at your school, in the back of big and expensive study guides, etc. However, these paper versions, even if essential, do not put much time pressure onto you, even while timing with a clock. This online version - available on the SAT College Board website ? gives a much greater sense of the time limitations, and you might take it more seriously for being done on the official website. Each section is timed like in the exam, and you may even write the essay and print it out later. In the end, you can score yourself and ask your tutor or teacher to score your essay (don't ask your parents, you know they'll be lenient). I think this definitely the best way to do a mock-exam.
The CollegeBoard website was used mainly as a diversity tool. It was not my main study resource.
The online practice help I found to be helpful to a point. There are not as many practice questions as I would've liked. Once they've been taken memory of the same questions will hinder learning as they are remembered. The addition of several more practice tests with explanations in identifying the correct answers would be an improvement to this resource.
The question of the day was helpful in identifying what skills needed improving on. The questions offered an explanation of how to solve the presented problem. If I missed the problem I was able to take it to my other resources and improve my skills.
I would recommend The CollegeBoard to students studying the SAT because it is a free service to students that will diversify their learning resource base. As this is an online service, answers and help with problems are instantaneous.
