The right difficulty level for Quant

I was getting overwhelmed with the Quant tests from other products, before someone recommended me to the GMAT Club Quant tests. I took the advice, and solved a test almost every day for 2 weeks. I didn't get the best scores, but it was pretty confidence boosting, since the difficulty level was just apt, and the large number of questions gave me a good practice that I needed. I scored upto 48 or 49 in some tests, and ended up scoring 49 in the real test. Although some of the questions carry the same style/theme with different numerical values, this is probably required to practice more and more. I used the bookmark feature extensively, and went back to the incorrect questions again and again after couple of days every time to give me sufficient preparation and the confidence that I have a good shot at the actual GMAT level of questions!
