Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
by the way, startupaddict, did you know that if you score an 800 on the gmat, you can't take it for 5 yrs! so if you're a gmat tutor, that wouldn't be good! you wont' be able to see any modifications to the real gmat if the test makers implement any changes. _________________
17 right, 4 wrong. Completed in 13 minutes. The errors were just stupid mistakes-- one of my clients showed me a list of idioms a class gave her, and I saw between X *OR* Y on there, and I started to second guess myself and picked that. Of course between X OR Y is always wrong (should be between X and Y).
I didn't do too much else today, bought some jeans, a jawbone 2, some lightscribe dvds to burn questions onto for clients.... worked the phone for 4 hours today, 7 clients ahhh. I should double as a shrink.
Tomorrow I have 2 appointments, maybe 3-- then if my brain is still working I plan to do 3 hours in the evening.
Oh actually I'm going to review those Quants I got wrong yesterday. There were 2 good ones that I can learn from.
Have been trying to PM you but i think you have blocked PM.
I don't know what's wrong with my PM's? I just tried having it automatically delete messages if my box is full, although it does not appear to be full............ hrm strange....... I just sent you a message. Let me know if you got it or not.
Here's the thing that ticks me off. LOGICALLY, we can assume they're all alive initially (otherwise how would Tina have a freaking name?). So in 4 years Tina would be at least 4, hence III should *logically* be true.
But, alas, the DS nazi who writes the DS questions says nope, you can't assume that.... so basically Tina isn't born yet.
So III need not be true.
So just remember, when doing age questions, don't assume the person is already born
You're a tutor? How much are you charging? You meeting up at his/your house or at school? You doing this by yourself or through some kind of organization? Would be a good way for me to make some money.
As for the question itself.
I is obviously false. II is oviously true. And we need to have a closer look at III
R = Rose S = Sam T = Tina
Today Rose is twice as old as Sam and Sam is 3 years younger than Tina. If Rose, Sam, and Tian are all alive 4 years from Today, which of the following must be true on that day?
Formulas: R = 2S S = T-3
Then to see whether it has to be true, you can just plug in the lowest number you can think of that work. R:2 S:1 T:4
4 years later: R:6 S:5 T:8
Hence, Tina CAN be older then Rose.
I - Rose is twice as old as Sam II - Sam is 3 years younger than Tina III - Rose is older than Tina
A) I only B) II only C) III only D) I and II E) II and III
Glad to have been of help.
For the record... I'm taking the GMAT on tuesday. Been studying 2-3 hours a day for a month. Did 4 prep. tests so far: 49Q, 46V, 770 49Q, 50V, 770 50Q, 44V, 770 49Q, 44V, 760
Would be really really happy with a 770.
EDIT: I'm an idiot. After proving that 3 was not necessarily true, I chose it in my answer. Whoops...

Does anyone have some hard Official questions Quant questions, ie tricky permutation/probability, geometry triples, etc?
Best of luck on your exam. One thing I would recommend would be focusing on the hard Quant questions you got right-- you're at 49/50, which means you're missing a lot of the harder questions. And of course I hope you're using GMATPrep, not Kraplan.
As for my business, I'm independent. I'd stay away from the prep companies. In fact, a lot of my clients come to me after having taken a prep course-- the prep companies care more about $$ than they do about results, which is why they rarely ever show how their students do.
After proving that 3 wasn't necessarily true, I chose it in my answer... Went too fast.
