Data Sufficiency

pls let me know if anyone of u hs attempted 800score.com tests. and how much did you score with the maths part? I found DS tough in that!

Yes! I did. I strangely got a 58 once . No, I am not joking!
I advice you to ignore the score and use the 800score questions as PART of your unevaluated preparation.

so to say dt i shudnt bother much abt 800score.com scores??!!

I took the 800score test once and then never ever bothered to take the test again. It was a waste of time. The test was not at all adaptive, and its scoring was very weird.
As Neel said, you can still use the 800score. Its a good tool to improve your test taking stamina, or to work on your timing strategies. Just don't worry too much about the scores it produces.
For better evaluation use GMATprep software and practice tests by Manhattan.

Thanks Rijul - That is exactly what I wanted to say!
