SAT® Test 9/Oct. 2017 QAS Analysis, Answers, and Explanations

Over 11 hours - that's 154 questions - of in-depth analysis and instruction of Practice Test 9/Oct. 2017 QAS

The most common question I get from students preparing for the SAT® is, "What's the most effective way to improve on this test?" After tutoring over 700 students on the new SAT®, the qualities that my most improved students all have are an open-mindedness to think differently about learning, a relentlessness in practicing and mastering all content areas of this test, and an unceasing desire to understand and fix past mistakes that they make on real College Board® tests.

I created this site because I wanted to help those studying for this test to find video lessons and detailed solutions for all published practice test clearly explained in one place on the internet. I've incorporated into these videos many of my test taking tips and strategies that are not found in prep courses. Watch the videos in sequence and deconstruct the test with me as I analyze entire reading, grammar, and math sections, or watch a specific video on one particular problem that you had trouble with - it's up to you.

This course covers all 154 questions of the October 2017 QAS test, which is College Board® official practice test 9. Each question is presented as a separate lecture.

Overall course length: 11 hours and 4 minutes

All College Board practice tests can be found here.

I highly recommend buying the College Board's Blue Book, which contains eight practice tests.
