  1. Data Sufficiency for GMAT/CAT (Introduction Level-0) Energy By Satyadhar Joshi May 2011 Online Class http://www.freegregmatclass.com/ shivgan3@yahoo.com

  2. Content • Introduction • Questions of Data Sufficiency • Strategies for solving • Some examples • Conclusion • References

  3. About this Class • Tough questions of Data Sufficiency for CAT/GMAT with some strategies to solve them will be discussed. Modified question of some books will be solved so that you can benefit and hone(sharpen) your skills. • This session will help you to understand how to pick up and visualize, fine tune and strategically work for DS. The class is expected to be highly interactive so that I can solve your difficulties and remove your fears about the subject.

  4. Introduction • Session about Data Sufficiency • Strategy more important than knowledge about the subject • You don’t have to solve the questions • We have to just conclude if it can be / or cannot be solved with the given data • The questions are mathematical or logical • Tricks and shortcuts explored • Practice Session • Confidence building measure taken up

  5. Areas of DS • Substitution • Defined Functions • Number Theory • Geometry • Coordinate Geometry • Inequalities • Fractions & Decimals • Equations • Averages & Statistics • Ratio & Proportion • Exponents & Roots • Factoring • Algebraic Expressions • Percents • Graphs • Word Problems • Sequences & Series • Counting • Probability • Permutations & Combinations • Functions • Miscellaneous Problems

  6. Marking The correct answer to a question is A if statement (1) ALONE is sufficient to answer the question but statement (2) alone is not sufficient; B if statement (2) ALONE is sufficient to answer the question but statement (1) alone is not sufficient; C if the two statements TAKEN TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient; D if EACH statement ALONE is sufficient to answer the question; E if the two statements TAKEN TOGETHER are still NOT sufficient to answer the question.

  7. Unwarranted Assumptions • How our wrong assumption can cause disaster in the exam • You must be very careful not to assume any more than what is explicitly given in a Data Sufficiency problem • Like natural, positive, real etc

  8. Checking Extreme Values • Boundary condition helps us a lot

  9. Degree of Freedom Paradigm • X+y+z=5 • In triangles Page 24, GMAT Data Sufficiency Prep course Nova

  10. Constrains of Examiner • Never will you question sufficient alone

  11. Strategy for Elimination • My personal advice is that go for a sure answer in this area, or go for very full-proof elimination Page 418, Book: GMAT Nova Math bible

  12. Strategy & tools • Never solve • Substitution
