Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Properties of 0






2. 3rd Rule of Probability: Conditional Probability






3. 2n+1 - 2n+3 - 2n+5






4. 5/6 = what %






5. Multiplication principle






6. 1. A and B < A or B 2. A or B > Individual probabilities of A - B 3. P(A and B) = P(A) x P(B) <-- 'fewer options' 4. P(A or B) = P(A) + P(B) <-- 'more options' - Probability of multiple events rules.






7. Volume of a sphere






8. Prime Factorization to find Greatest Common Factor






9. How to check whether number is multiple of 9






10. Quadratic formula






11. Number of integers from A to B inclusive = B - A + 1 - How many consecutive integers are there from 73 through 419 - inclusive?






12. If you have to guess in a problem - which ones should you guess? Especially if you have to plug numbers.






13. How many liters of a solution that is 10% alcohol by volume must be added to 2 liters of a solution that is 50% alcohol by volume to create a solution that is 15% alcohol by volume?






14. The number of outcomes that result in A divided by the total number of possible outcomes.






15. Permutations: Order Matters






16. Multiples of 3






17. Odd Factors






18. Inscribed Angle - Minor Arc






19. Sum of consecutive numbers






20. Compound interest formula






21. Combined Events: E and F






22. Some GMAT word problems involve groups with distinct 'either/or' categories (male/female - blue collar/white collar - etc.) The key is to do what with the information? 1. Find total number of possible outcomes. 2. Find the number of desired outcomes.

24. When you see an equation in factored form in a question?






25. The average of consecutive numbers






26. Gross






27. Odd and Even rule.






28. Simple probability






29. Simple Interest Formula (remember this is the total amount of money in the bank after the interest is earned)






30. Trial Problems: look at the probability of NOT OCCURRING






31. Combined Events: E or F






32. Indistinguishable events how to find the number of permutations

37. How to check whether a number is a multiple of 4.






38. Combined Events: Not E = P(not E) = ?






39. Intersecting Sets
