Flashcards in Plan B Strategies Deck (11):
am I missing anything? (Break it out)
Approximation - when to round?
If the problem contains difficult numbers, AND a phrase that means "approximately"
Subtract common elements - (for quantitative comparison questions)
(These are not always obvious)
Using the answers - backsolving
Plugging the answer choices back into the question in order to solve it (less han 10% of GRE math problems can be solved by backsolving)
Try A, then E, then D, C, B
Check the answers for clues!
While you're solving...
When the problem contains NO CONCRETE values
But if picking numbers for problems involving MULTIPLES, FACTORS or REMAINDERS, pick several numbers
"Ass"ign "whole" numbers to variables in the question:
1. Replace all variables in the problem by picking numbers, then solve the problem using those numbers
2. Plug the values you've picked for the variables into the answer choices to see which one matches your solution
[avoid 0, 1, 100]
Split the answers
"Split the answers"into a big group or a little group (works for problem solving questions - always in order!)
Pick a test number
Should not be one of the answer choices - choose one that splits the answers into a group bigger than the number you choose and a group smaller
