sudhansu9dm, I assume you're referring to an incident in which a company disclosed *live* test questions and got shut down.
1000SC is NOT that set of questions leaked by a banned company. The 1000 series / sets have been around for a very long time. They are a mixture of real, legally published past test questions from before the GMAT was an adaptive test and other random questions from unknown sources.
There are a number of good questions in the 1000 sets. There are a number of bad questions. There are also questions that were once good questions but had errors or typos entered in when they began being distributed on the Internet and those errors have not been fixed. I once entered into a lengthy discussion over on Beat The GMAT in which everyone was trying to justify the correct SC answer but struggling to do so. The "correct" answer had an error introduced at some point along the way and was no longer actually correct. I've seen others on which the "official" answer was listed as, say, B, when the correct answer was really C.
So. Personally, I can usually tell when a question is a good one or a bad one. That's because I've been doing this for 15 years and it's my job. My students typically can't tell reliably, so I tell them to avoid these questions.
Also, there are so many other great and more recent sources out there, that I wouldn't personally bother with the 1000 sets. Even the ones that are good are from the paper-and-pencil era of the GMAT - which ended in 1997.
