Every question has a detailed solution with answers. So that's not true.

All questions have links to the discussions on Gmat Club forum in case of any questions.

This is what exactly I was looking for. Is there any way we can get tagged questions in Document format to download?

A goal without a plan is just a wish.
You can go higher, you can go deeper, there are no boundaries above or beneath you.

Thanks...so do you suggest I go through these questions only after I've gone through the CATs I have?
