GMAT

So I am doing these practice tests.....how many should I be getting right out of 10 questions to be doing well?

I think I have become stupid being out of school for 10 years.

Are you doing them out of the book,or on a computer? Because the actual test adjusts to you, and if you think the questions are easy, it's cause the test thinks you are stupid.

Heh, impossible to say for the very reason royalfan mentioned.

Piece of advice though: The sum of the first 100 integers is 5050.

And that is important stuff. No way you can backstab your way to middle management without knowing that the sum of the first hundred integers is 5050.

Good luck on the GMAT and where ever you decide to go to B-School.

Well, yeah. Who doesn't know that?

50*(100+1)=5050.

[Vaevictis]

Heh, I didn't know that.

I ended up figuring it out, but it took me a minute.

My thought is that if you are smart enough to post on Soonerfans.com; you should probably get at least a 720 without studying.

100+99+98+...+ 3 +2 +1 PLUS
1 + 2+ 3 +...+98+99+100 EQUALS
101+101+101..+101+101+101 Which IS

100*(101) but you doubled the count so you need to divide by 2 hence the formula (N*(N+1))/2
