origin of 1000 RC

[aim-wsc]

If you've downloaded it from this forums, you perhaps have read the preceding discussion about it which would give you some idea of this doc.

But it seems that you've not checked that sticky thread & downloaded it from some other source. Otherwise you would've called it 3000RC .

Anyways, as per the source of the doc, scoretop had compiled this document.
You will see passeges from GRE, GMAT & LSAT syllabus
but they are good for practising.

PS. check out that sticky thread where the doc is available. I've talked on similar lines there...will be helpful to you 8)
