What does test anxiety really look like on the GMAT? For many test takers, it does not look like a panic attack. Instead, it shows up as brain fog, rereading, negative comparisons, mental noise....

Dear all,
Assuming you solve an exercise with the following solutions:
x_1=-1,
x_2=-1,
x_3=5,
x_4=5
Do the following questions result in different answers?
What is the convention with respect to unique vs all possible solutions on the GMAT
(in what way does the GMAT ask for various combinations of above stated solutions)?
Thank you very much for your help (Kudos will be given).
Kind regards.

(in what way does the GMAT ask for various combinations of above stated solutions)?
- What is the sum of all unique solutions?
- What is the sum of all possible solutions?
- What is the sum of all possible values?
Thank you very much for your help (Kudos will be given).

Hi ghnlrug,
In general, most GMAT questions ask a straight-forward question (re: What is the value of X? Is Y/Z an integer? What does the scientist assume about the study? Etc.), but as you perform at higher-and-higher levels, the Test will adapt to you - and you'll be more likely to see questions that 'test' the thoroughness of your thinking. While you won't necessarily see lots of questions in that format (even if you're doing really well overall), you might see questions that require more effort (re: What is the sum of all of the possible values of X?). Based on the wording of the question, you can infer that more work might be needed; in the prior example, note how the prompt did NOT ask for the value of X or the "sum of the two values of X" - it asked for the sum of ALL of the possible values of X).
Regardless of what specific question is asked, your focus should be on doing organized, strategic work on your pad (NEVER "in your head") because that's the most efficient way to approach just about every question on the GMAT (and that's what Business Schools will expect of you). You should also keep in mind that NOTHING about a GMAT question is ever "random" - every word in each question is carefully chosen (and even the format of the 5 answer choices is carefully chosen) so you should pay careful attention to those details. You'll find that most questions require 3-5 'steps', but the individual steps are rarely all that difficult - and if you think that a question is too hard or too weird, then you should 'dump it' and move on.

What is the sum of all unique solutions?
Sum of all unique solutions = 0 sine there is no unique solution
What is the sum of all possible solutions?
Sum of all possible solutions = -1 -1 +5 +5 = 8
What is the sum of all possible values?
Sum of all possible values = -1 + 5 = 4

Are you sure about this? Because you could also think it means summing all those answers that appear twice only once, e.g.,
-1+5=4
