Is 1000 sc a good resource to use?

[kshitijg17]

Hi !
I am guessing that this is the correct place to post this query.
I have recently come across a source known as 1000SC ... supposedly it is close to GMAT level questions .
Since there seem to be no solutions to them but only an answer key. I wanted to know if using such a source would be worth the effort?
I am currently using this forum and Mgmat verbal material for sc.

We have banned that source here, actually. There are a number of good problems in there, but there are a number of errors as well - I've seen SCs in there that have no right answer. I've seen SCs where the correct answer is mislabeled and then I'd get people asking, "I don't get it, why is C the right answer?" and I'd have to say, "It's not. B is the right answer." Meanwhile, they've been memorizing C as correct...

So, really, I wouldn't use it - because you don't want to be wondering whether what you're learning is actually valid or whether you're learning something that's actually wrong!
