Hi, sorry but I had to delete your post. 1000SC is a banned source because it illegally uses copyrighted oproblems without permission. (And, even if it didn't, we'd ban it anyway - a lot of the problems in the set are fine, but there are a number of bad ones that can actually mess up your study if you use them!)
