  2. Task1: • What is the SAT exam? • The SAT and SAT Subject Tests are a suite of tools designed to assess your academic readiness for college. These exams provide a path to opportunities, financial support and scholarships, in a way that's fair to all students. • The SAT and SAT Subject Tests keep pace with what colleges are looking for today, measuring the skills required for success in the 21st century. • What is the target score for ATHS students? • 600 • Subscores on the SAT Subject Tests are used to compute the total score, but their individual contributions differ between the different tests. Subscores are reported on a 20-80 scale. For the French, German, and Spanish with Listening tests, the reading subscore counts twice as much as the listening subscore. For the Chinese, Japanese, and Korean tests, subscores are weighted equally.

  3. How the SAT test is scored?

  4. We do a statistical analysis to make sure the test is an accurate representation of your skills. The unscored section of the test also helps us ensure the test is fair. Questions in the unscored section are not factored into your SAT score. • In our statistical analysis, equating adjusts for slight differences in difficulty between test editions and ensures that a student's score of, say, 450 on one edition of a test reflects the same ability as a score of 450 on another edition of the test. Equating also ensures that a student's score does not depend on how well others did on the same edition of the test. • Every SAT includes a 25-minute section, which doesn't count toward your final score. It may be a critical reading, mathematics, or multiple-choice writing section. • We do this because it helps us assess questions for next year's test, and it ensures that the SAT accurately reflects your skills. Also, the unscored section helps us account for minor differences in difficulty across all the different forms of the test.

  5. Your raw score is then converted to a scaled score (reported on a 200-800 scale) by a statistical process called equating. Equating ensures that the different forms of the test or the level of ability of the students with whom you are tested do not affect your score. Equating makes it possible to make comparisons among test takers who take different editions of the test across different administrations. • Mention 10 tips to score more in SAT. • 1. Build your own vocabulary list using past tests. • 2. For Critical Reading passage based questions, experiment with different strategies. • 3. Know your special triangles. • 4. Never leave any multiple choice questions blank. • 5. Read, read, read—especially topics that you don’t find particularly interesting. • 6. If you're stuck on a math problem, start writing. • 7. In your essay, consider the opposing point of view. • 8. Always show your work. • 9. Use official tests to practice with. • 10. Create a collection of mature sounding words and phrases to incorporate into your essay. • What is the minimum number of correct answers you need in each section to reachthe target? • 600 (200 in each section).

  6. Task2: SAT questions.

  7. Task3: • Given the sequence: 11, 7, 3, -1, ...  • Determine the type of sequence?  Arithmetic sequence  • Find the next three terms of the sequence. ( -5,-9,-13) • Write a formula for the sequence.an = a1 + (n – 1)d • In your own language write about this type of sequences.  If a sequence of values follows a pattern of adding a fixed amount from one term to the next, it is referred to as an  arithmetic sequence.  • Given the sequence: 5, 25, 125, 625, ...  • Determine the type of sequence? Geometric sequence  • Find the next three terms of the sequence.  ( 3125 ,15625 ,78125) • Write a formula for the sequence.Xn = ar(n-1) • In your own language write about this type of sequences. In a Geometric Sequence each term is found by multiplying the previous term by a constant. • Given the sequence: 0, 1, 1, 2, 3, .....  • Determine the type of sequence?  Fibonacci Sequence • Find the next three terms of the sequence. ( 5 ,8 ,13 ) • Write a formula for the sequence.xn = xn-1 + xn-2 OR x6 = x5+ x4 • In your own language write about this type of sequences. The next number is found by adding up the two numbers before it.
