Thanks for the post. I am sorry you are feeling this way. The tests are designed for those looking to break the Q50 ceiling and are punitive to those who may be looking for a Q45 and are at a Q40 level. The tests were designed to fill a gap in the Hard and Extra Hard Quant categories and put one to the test in areas that are covered on the GMAT but not often explored such as behavior fractions. It is a pretty basic concept that we all know but becomes a fascinating subject once you add powers to it, and suddenly 1/8 is smaller than 1/2 but then add negative to a fraction and it flips everything upside down. This is not something you will see on an average question and average is something we did NOT want to be.
We are probably a bit old-school and hardcore in our approach - when we created the tests, as test-takers, we felt character was forged rather than nurtured (there are times for both but we were not good at nurturing side of things). We focused on forging, believing that an ounce of sweat saves a gallon of blood. Thus when you go to face the beast itself, you will be adequately armed and prepared with scars and training that will serve you well. And while there is a lot to say about how success motivates and fuels one's desire to persevere,
GMAT Club tests have that as well, they just don't give you second chances, but one feels a lot more rewarded conquering a tough enemy rather than a pushover.
The tests do have a pre-requisite of certain level of skills and knowledge. You are welcome to contact support put the subscription on hold and come back to them once you get stronger footing, or even get a refund. Generations of moderators stand behind the
GMAT Club tests and we definitely won't be offended if it is not your cup of tea - we respect that.
