No offence, but the gap here is about as large as the grand canyon. I mean, just look at this one question. I will use it as an example.
"If a tree branch can hold three people and John weighs twice as much as Adam, and Rachel weighs half as much as Adam, then Rachel, John and Adam can all sit together on the tree branch safely."
By definition, they are 3 people, so they can sit on the branch safely. What is there to dispute? branch holds 3 people. We have John, Adam, and Rachel. 3 people. Unless I missed something. Weight is never discussed. How do we know that John is not a 4 month old baby? If you do the math on this ( how they want you to mind you ) then John = 2 Adam =1 Rachel = 1/2. Therefore 2+1+.5 = more than 3, so branch not hold. Now if it said that John is twice a normal person, than it would hold true. The correct answer to this question should be true, but if you check "true" then your score goes down, if all the other questions are answered the same way.
It's numbers. They don't lie
