Gmat club tests -Quant

I had given a few GMAT club quant tests before attempting my actual GMAT.
The difficulty level is at par with the actual GMAT test. You will be able to cover all the topics in Quants with the help of these tests. The analysis is also very detailed. However, you cannot trust the actual score that is provided. I dont think they have got the algorithm right. I remember in my second test , even after getting more incorrect easy questions I was able to score higher than my first one. But it is a blessing for people who want to cover all topics in Quants. I am the kind of person who studies via mocks. I lose concentration if I read topic wise. So it was extremely helpful to me.
