While the judgment process has rules, many of your choices are a matter of opinion, especially as to whether or not one thing vaguely relates to another. In the end, that ends up being your view versus that of the person who wrote the "practice query". With that aside, there have been plenty of times that I followed the rules to the point and was told my answer was incorrect. The job is far more frustrating than the pay is worth, and you will find yourself only able to work 10-15 minutes straight before needing to take a break. If you can somehow avoid your own human tendencies to use common sense and logic, then maybe this job is for you! Let's not forget, there is ZERO room for advancement, and since you are an independent contractor, when the contract ends, so does your money!
